      20     TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
      21
      22     1. Definitions.
      23
      24        "License" shall mean the terms and conditions for use, reproduction,
      25        and distribution as defined by Sections 1 through 9 of this document.
      26
      27        "Licensor" shall mean the copyright owner or entity authorized by
      28        the copyright owner that is granting the License.
      29
      30        "Legal Entity" shall mean the union of the acting entity and all
      31        other entities that control, are controlled by, or are under common
      32        control with that entity. For the purposes of this definition,
      33        "control" means (i) the power, direct or indirect, to cause the
      34        direction or management of such entity, whether by contract or
      35        otherwise, or (ii) ownership of fifty percent (50%%) or more of the
      36        outstanding shares, or (iii) beneficial ownership of such entity.
      37
      38        "You" (or "Your") shall mean an individual or Legal Entity
      39        exercising permissions granted by this License.

      41        "Source" form shall mean the preferred form for making modifications,
      42        including but not limited to software source code, documentation
      43        source, and configuration files.
      44
      45        "Object" form shall mean any form resulting from mechanical
      46        transformation or translation of a Source form, including but
      47        not limited to compiled object code, generated documentation,
      48        and conversions to other media types.
      49
      50        "Work" shall mean the work of authorship, whether in Source or
      51        Object form, made available under the License, as indicated by a
      52        copyright notice that is included in or attached to the work
      53        (an example is provided in the Appendix below).
      54
      55        "Derivative Works" shall mean any work, whether in Source or Object
      56        form, that is based on (or derived from) the Work and for which the
      57        editorial revisions, annotations, elaborations, or other modifications
      58        represent, as a whole, an original work of authorship. For the purposes
      59        of this License, Derivative Works shall not include works that remain
      60        separable from, or merely link (or bind by name) to the interfaces of,
      61        the Work and Derivative Works thereof.
      62
      63        "Contribution" shall mean any work of authorship, including
      64        the original version of the Work and any modifications or additions
      65        to that Work or Derivative Works thereof, that is intentionally
      66        submitted to Licensor for inclusion in the Work by the copyright owner
      67        or by an individual or Legal Entity authorized to submit on behalf of
      68        the copyright owner. For the purposes of this definition, "submitted"
      69        means any form of electronic, verbal, or written communication sent
      70        to the Licensor or its representatives, including but not limited to
      71        communication on electronic mailing lists, source code control systems,
      72        and issue tracking systems that are managed by, or on behalf of, the
      73        Licensor for the purpose of discussing and improving the Work, but
      74        excluding communication that is conspicuously marked or otherwise
      75        designated in writing by the copyright owner as "Not a Contribution."
      76
      77        "Contributor" shall mean Licensor and any individual or Legal Entity
      78        on behalf of whom a Contribution has been received by Licensor and
      79        subsequently incorporated within the Work.
      80
      81     2. Grant of Copyright License. Subject to the terms and conditions of
      82        this License, each Contributor hereby grants to You a perpetual,
      83        worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      84        copyright license to reproduce, prepare Derivative Works of,
      85        publicly display, publicly perform, sublicense, and distribute the
      86        Work and such Derivative Works in Source or Object form.
      87
      88     3. Grant of Patent License. Subject to the terms and conditions of
      89        this License, each Contributor hereby grants to You a perpetual,
      90        worldwide, non-exclusive, no-charge, royalty-free, irrevocable
      91        (except as stated in this section) patent license to make, have made,
      92        use, offer to sell, sell, import, and otherwise transfer the Work,
      93        where such license applies only to those patent claims licensable
      94        by such Contributor that are necessarily infringed by their
      95        Contribution(s) alone or by combination of their Contribution(s)
      96        with the Work to which such Contribution(s) was submitted. If You
      97        institute patent litigation against any entity (including a
      98        cross-claim or counterclaim in a lawsuit) alleging that the Work
      99        or a Contribution incorporated within the Work constitutes direct
     100        or contributory patent infringement, then any patent licenses
     101        granted to You under this License for that Work shall terminate
     102        as of the date such litigation is filed.
     103
     104     4. Redistribution. You may reproduce and distribute copies of the
     105        Work or Derivative Works thereof in any medium, with or without
     106        modifications, and in Source or Object form, provided that You
     107        meet the following conditions:
     108
     109        (a) You must give any other recipients of the Work or
     110            Derivative Works a copy of this License; and
     111
     112        (b) You must cause any modified files to carry prominent notices
     113            stating that You changed the files; and
     114
     115        (c) You must retain, in the Source form of any Derivative Works
     116            that You distribute, all copyright, patent, trademark, and
     117            attribution notices from the Source form of the Work,
     118            excluding those notices that do not pertain to any part of
     119            the Derivative Works; and
     120
     121        (d) If the Work includes a "NOTICE" text file as part of its
     122            distribution, then any Derivative Works that You distribute must
     123            include a readable copy of the attribution notices contained
     124            within such NOTICE file, excluding those notices that do not
     125            pertain to any part of the Derivative Works, in at least one
     126            of the following places: within a NOTICE text file distributed
     127            as part of the Derivative Works; within the Source form or
     128            documentation, if provided along with the Derivative Works; or,
     129            within a display generated by the Derivative Works, if and
     130            wherever such third-party notices normally appear. The contents
     131            of the NOTICE file are for informational purposes only and
     132            do not modify the License. You may add Your own attribution
     133            notices within Derivative Works that You distribute, alongside
     134            or as an addendum to the NOTICE text from the Work, provided
     135            that such additional attribution notices cannot be construed
     136            as modifying the License.
     137
     138        You may add Your own copyright statement to Your modifications and
     139        may provide additional or different license terms and conditions
     140        for use, reproduction, or distribution of Your modifications, or
     141        for any such Derivative Works as a whole, provided Your use,
     142        reproduction, and distribution of the Work otherwise complies with
     143        the conditions stated in this License.
     144
     145     5. Submission of Contributions. Unless You explicitly state otherwise,
     146        any Contribution intentionally submitted for inclusion in the Work
     147        by You to the Licensor shall be under the terms and conditions of
     148        this License, without any additional terms or conditions.
     149        Notwithstanding the above, nothing herein shall supersede or modify
     150        the terms of any separate license agreement you may have executed
     151        with Licensor regarding such Contributions.
     152
     153     6. Trademarks. This License does not grant permission to use the trade
     154        names, trademarks, service marks, or product names of the Licensor,
     155        except as required for reasonable and customary use in describing the
     156        origin of the Work and reproducing the content of the NOTICE file.
     157
     158     7. Disclaimer of Warranty. Unless required by applicable law or
     159        agreed to in writing, Licensor provides the Work (and each
     160        Contributor provides its Contributions) on an "AS IS" BASIS,
     161        WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
     162        implied, including, without limitation, any warranties or conditions
     163        of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
     164        PARTICULAR PURPOSE. You are solely responsible for determining the
     165        appropriateness of using or redistributing the Work and assume any
     166        risks associated with Your exercise of permissions under this License.
     167
     168     8. Limitation of Liability. In no event and under no legal theory,
     169        whether in tort (including negligence), contract, or otherwise,
     170        unless required by applicable law (such as deliberate and grossly
     171        negligent acts) or agreed to in writing, shall any Contributor be
     172        liable to You for damages, including any direct, indirect, special,
     173        incidental, or consequential damages of any character arising as a
     174        result of this License or out of the use or inability to use the
     175        Work (including but not limited to damages for loss of goodwill,
     176        work stoppage, computer failure or malfunction, or any and all
     177        other commercial damages or losses), even if such Contributor
     178        has been advised of the possibility of such damages.
     179
     180     9. Accepting Warranty or Additional Liability. While redistributing
     181        the Work or Derivative Works thereof, You may choose to offer,
     182        and charge a fee for, acceptance of support, warranty, indemnity,
     183        or other liability obligations and/or rights consistent with this
     184        License. However, in accepting such obligations, You may act only
     185        on Your own behalf and on Your sole responsibility, not on behalf
     186        of any other Contributor, and only if You agree to indemnify,
     187        defend, and hold each Contributor harmless for any liability
     188        incurred by, or claims asserted against, such Contributor by reason
     189        of your accepting any such warranty or additional liability.
     190
     191     END OF TERMS AND CONDITIONS
     192
     193     APPENDIX: How to apply the Apache License to your work.
     194
     195        To apply the Apache License to your work, attach the following
     196        boilerplate notice, with the fields enclosed by brackets "[]"
     197        replaced with your own identifying information. (Don't include
     198        the brackets!)  The text should be enclosed in the appropriate
     199        comment syntax for the file format. We also recommend that a
     200        file or class name and description of purpose be included on the
     201        same "printed page" as the copyright notice for easier
     202        identification within third-party archives.

     279                         Version 3, 19 November 2007
     280
     281   Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
     282   Everyone is permitted to copy and distribute verbatim copies
     283   of this license document, but changing it is not allowed.
     284
     285                              Preamble
     286
     287    The GNU Affero General Public License is a free, copyleft license for
     288  software and other kinds of works, specifically designed to ensure
     289  cooperation with the community in the case of network server software.
     290
     291    The licenses for most software and other practical works are designed
     292  to take away your freedom to share and change the works.  By contrast,
     293  our General Public Licenses are intended to guarantee your freedom to
     294  share and change all versions of a program--to make sure it remains free
     295  software for all its users.
     296
     297    When we speak of free software, we are referring to freedom, not
     298  price.  Our General Public Licenses are designed to make sure that you
     299  have the freedom to distribute copies of free software (and charge for
     300  them if you wish), that you receive source code or can get it if you
     301  want it, that you can change the software or use pieces of it in new
     302  free programs, and that you know you can do these things.
     303
     304    Developers that use our General Public Licenses protect your rights
     305  with two steps: (1) assert copyright on the software, and (2) offer
     306  you this License which gives you legal permission to copy, distribute
     307  and/or modify the software.
     308
     309    A secondary benefit of defending all users' freedom is that
     310  improvements made in alternate versions of the program, if they
     311  receive widespread use, become available for other developers to
     312  incorporate.  Many developers of free software are heartened and
     313  encouraged by the resulting cooperation.  However, in the case of
     314  software used on network servers, this result may fail to come about.
     315  The GNU General Public License permits making a modified version and
     316  letting the public access it on a server without ever releasing its
     317  source code to the public.
     318
     319    The GNU Affero General Public License is designed specifically to
     320  ensure that, in such cases, the modified source code becomes available
     321  to the community.  It requires the operator of a network server to
     322  provide the source code of the modified version running there to the
     323  users of that server.  Therefore, public use of a modified version, on
     324  a publicly accessible server, gives the public access to the source
     325  code of the modified version.
     326
     327    An older license, called the Affero General Public License and
     328  published by Affero, was designed to accomplish similar goals.  This is
     329  a different license, not a version of the Affero GPL, but Affero has
     330  released a new version of the Affero GPL which permits relicensing under
     331  this license.
     332
     333    The precise terms and conditions for copying, distribution and
     334  modification follow.
     335
     336                         TERMS AND CONDITIONS
     337
     338    0. Definitions.
     339
     340    "This License" refers to version 3 of the GNU Affero General Public License.
     341
     342    "Copyright" also means copyright-like laws that apply to other kinds of
     343  works, such as semiconductor masks.
     344
     345    "The Program" refers to any copyrightable work licensed under this
     346  License.  Each licensee is addressed as "you".  "Licensees" and
     347  "recipients" may be individuals or organizations.
     348
     349    To "modify" a work means to copy from or adapt all or part of the work
     350  in a fashion requiring copyright permission, other than the making of an
     351  exact copy.  The resulting work is called a "modified version" of the
     352  earlier work or a work "based on" the earlier work.
     353
     354    A "covered work" means either the unmodified Program or a work based
     355  on the Program.
     356
     357    To "propagate" a work means to do anything with it that, without
     358  permission, would make you directly or secondarily liable for
     359  infringement under applicable copyright law, except executing it on a
     360  computer or modifying a private copy.  Propagation includes copying,
     361  distribution (with or without modification), making available to the
     362  public, and in some countries other activities as well.
     363
     364    To "convey" a work means any kind of propagation that enables other
     365  parties to make or receive copies.  Mere interaction with a user through
     366  a computer network, with no transfer of a copy, is not conveying.
     367
     368    An interactive user interface displays "Appropriate Legal Notices"
     369  to the extent that it includes a convenient and prominently visible
     370  feature that (1) displays an appropriate copyright notice, and (2)
     371  tells the user that there is no warranty for the work (except to the
     372  extent that warranties are provided), that licensees may convey the
     373  work under this License, and how to view a copy of this License.  If
     374  the interface presents a list of user commands or options, such as a
     375  menu, a prominent item in the list meets this criterion.
     376
     377    1. Source Code.
     378
     379    The "source code" for a work means the preferred form of the work
     380  for making modifications to it.  "Object code" means any non-source
     381  form of a work.
     382
     383    A "Standard Interface" means an interface that either is an official
     384  standard defined by a recognized standards body, or, in the case of
     385  interfaces specified for a particular programming language, one that
     386  is widely used among developers working in that language.
     387
     388    The "System Libraries" of an executable work include anything, other
     389  than the work as a whole, that (a) is included in the normal form of
     390  packaging a Major Component, but which is not part of that Major
     391  Component, and (b) serves only to enable use of the work with that
     392  Major Component, or to implement a Standard Interface for which an
     393  implementation is available to the public in source code form.  A
     394  "Major Component", in this context, means a major essential component
     395  (kernel, window system, and so on) of the specific operating system
     396  (if any) on which the executable work runs, or a compiler used to
     397  produce the work, or an object code interpreter used to run it.
     398
     399    The "Corresponding Source" for a work in object code form means all
     400  the source code needed to generate, install, and (for an executable
     401  work) run the object code and to modify the work, including scripts to
     402  control those activities.  However, it does not include the work's
     403  System Libraries, or general-purpose tools or generally available free
     404  programs which are used unmodified in performing those activities but
     405  which are not part of the work.  For example, Corresponding Source
     406  includes interface definition files associated with source files for
     407  the work, and the source code for shared libraries and dynamically
     408  linked subprograms that the work is specifically designed to require,
     409  such as by intimate data communication or control flow between those
     410  subprograms and other parts of the work.
     411
     412    The Corresponding Source need not include anything that users
     413  can regenerate automatically from other parts of the Corresponding
     414  Source.
     415
     416    The Corresponding Source for a work in source code form is that
     417  same work.
     418
     419    2. Basic Permissions.
     420
     421    All rights granted under this License are granted for the term of
     422  copyright on the Program, and are irrevocable provided the stated
     423  conditions are met.  This License explicitly affirms your unlimited
     424  permission to run the unmodified Program.  The output from running a
     425  covered work is covered by this License only if the output, given its
     426  content, constitutes a covered work.  This License acknowledges your
     427  rights of fair use or other equivalent, as provided by copyright law.
     428
     429    You may make, run and propagate covered works that you do not
     430  convey, without conditions so long as your license otherwise remains
     431  in force.  You may convey covered works to others for the sole purpose
     432  of having them make modifications exclusively for you, or provide you
     433  with facilities for running those works, provided that you comply with
     434  the terms of this License in conveying all material for which you do
     435  not control copyright.  Those thus making or running the covered works
     436  for you must do so exclusively on your behalf, under your direction
     437  and control, on terms that prohibit them from making any copies of
     438  your copyrighted material outside their relationship with you.
     439
     440    Conveying under any other circumstances is permitted solely under
     441  the conditions stated below.  Sublicensing is not allowed; section 10
     442  makes it unnecessary.
     443
     444    3. Protecting Users' Legal Rights From Anti-Circumvention Law.
     445
     446    No covered work shall be deemed part of an effective technological
     447  measure under any applicable law fulfilling obligations under article
     448  11 of the WIPO copyright treaty adopted on 20 December 1996, or
     449  similar laws prohibiting or restricting circumvention of such
     450  measures.
     451
     452    When you convey a covered work, you waive any legal power to forbid
     453  circumvention of technological measures to the extent such circumvention
     454  is effected by exercising rights under this License with respect to
     455  the covered work, and you disclaim any intention to limit operation or
     456  modification of the work as a means of enforcing, against the work's
     457  users, your or third parties' legal rights to forbid circumvention of
     458  technological measures.
     459
     460    4. Conveying Verbatim Copies.
     461
     462    You may convey verbatim copies of the Program's source code as you
     463  receive it, in any medium, provided that you conspicuously and
     464  appropriately publish on each copy an appropriate copyright notice;
     465  keep intact all notices stating that this License and any
     466  non-permissive terms added in accord with section 7 apply to the code;
     467  keep intact all notices of the absence of any warranty; and give all
     468  recipients a copy of this License along with the Program.
     469
     470    You may charge any price or no price for each copy that you convey,
     471  and you may offer support or warranty protection for a fee.
     472
     473    5. Conveying Modified Source Versions.
     474
     475    You may convey a work based on the Program, or the modifications to
     476  produce it from the Program, in the form of source code under the
     477  terms of section 4, provided that you also meet all of these conditions:
     478
     479      a) The work must carry prominent notices stating that you modified
     480      it, and giving a relevant date.
     481
     482      b) The work must carry prominent notices stating that it is
     483      released under this License and any conditions added under section
     484      7.  This requirement modifies the requirement in section 4 to
     485      "keep intact all notices".
     486
     487      c) You must license the entire work, as a whole, under this
     488      License to anyone who comes into possession of a copy.  This
     489      License will therefore apply, along with any applicable section 7
     490      additional terms, to the whole of the work, and all its parts,
     491      regardless of how they are packaged.  This License gives no
     492      permission to license the work in any other way, but it does not
     493      invalidate such permission if you have separately received it.
     494
     495      d) If the work has interactive user interfaces, each must display
     496      Appropriate Legal Notices; however, if the Program has interactive
     497      interfaces that do not display Appropriate Legal Notices, your
     498      work need not make them do so.
     499
     500    A compilation of a covered work with other separate and independent
     501  works, which are not by their nature extensions of the covered work,
     502  and which are not combined with it such as to form a larger program,
     503  in or on a volume of a storage or distribution medium, is called an
     504  "aggregate" if the compilation and its resulting copyright are not
     505  used to limit the access or legal rights of the compilation's users
     506  beyond what the individual works permit.  Inclusion of a covered work
     507  in an aggregate does not cause this License to apply to the other
     508  parts of the aggregate.
     509
     510    6. Conveying Non-Source Forms.
     511
     512    You may convey a covered work in object code form under the terms
     513  of sections 4 and 5, provided that you also convey the
     514  machine-readable Corresponding Source under the terms of this License,
     515  in one of these ways:
     516
     517      a) Convey the object code in, or embodied in, a physical product
     518      (including a physical distribution medium), accompanied by the
     519      Corresponding Source fixed on a durable physical medium
     520      customarily used for software interchange.
     521
     522      b) Convey the object code in, or embodied in, a physical product
     523      (including a physical distribution medium), accompanied by a
     524      written offer, valid for at least three years and valid for as
     525      long as you offer spare parts or customer support for that product
     526      model, to give anyone who possesses the object code either (1) a
     527      copy of the Corresponding Source for all the software in the
     528      product that is covered by this License, on a durable physical
     529      medium customarily used for software interchange, for a price no
     530      more than your reasonable cost of physically performing this
     531      conveying of source, or (2) access to copy the
     532      Corresponding Source from a network server at no charge.
     533
     534      c) Convey individual copies of the object code with a copy of the
     535      written offer to provide the Corresponding Source.  This
     536      alternative is allowed only occasionally and noncommercially, and
     537      only if you received the object code with such an offer, in accord
     538      with subsection 6b.
     539
     540      d) Convey the object code by offering access from a designated
     541      place (gratis or for a charge), and offer equivalent access to the
     542      Corresponding Source in the same way through the same place at no
     543      further charge.  You need not require recipients to copy the
     544      Corresponding Source along with the object code.  If the place to
     545      copy the object code is a network server, the Corresponding Source
     546      may be on a different server (operated by you or a third party)
     547      that supports equivalent copying facilities, provided you maintain
     548      clear directions next to the object code saying where to find the
     549      Corresponding Source.  Regardless of what server hosts the
     550      Corresponding Source, you remain obligated to ensure that it is
     551      available for as long as needed to satisfy these requirements.
     552
     553      e) Convey the object code using peer-to-peer transmission, provided
     554      you inform other peers where the object code and Corresponding
     555      Source of the work are being offered to the general public at no
     556      charge under subsection 6d.
     557
     558    A separable portion of the object code, whose source code is excluded
     559  from the Corresponding Source as a System Library, need not be
     560  included in conveying the object code work.
     561
     562    A "User Product" is either (1) a "consumer product", which means any
     563  tangible personal property which is normally used for personal, family,
     564  or household purposes, or (2) anything designed or sold for incorporation
     565  into a dwelling.  In determining whether a product is a consumer product,
     566  doubtful cases shall be resolved in favor of coverage.  For a particular
     567  product received by a particular user, "normally used" refers to a
     568  typical or common use of that class of product, regardless of the status
     569  of the particular user or of the way in which the particular user
     570  actually uses, or expects or is expected to use, the product.  A product
     571  is a consumer product regardless of whether the product has substantial
     572  commercial, industrial or non-consumer uses, unless such uses represent
     573  the only significant mode of use of the product.
     574
     575    "Installation Information" for a User Product means any methods,
     576  procedures, authorization keys, or other information required to install
     577  and execute modified versions of a covered work in that User Product from
     578  a modified version of its Corresponding Source.  The information must
     579  suffice to ensure that the continued functioning of the modified object
     580  code is in no case prevented or interfered with solely because
     581  modification has been made.
     582
     583    If you convey an object code work under this section in, or with, or
     584  specifically for use in, a User Product, and the conveying occurs as
     585  part of a transaction in which the right of possession and use of the
     586  User Product is transferred to the recipient in perpetuity or for a
     587  fixed term (regardless of how the transaction is characterized), the
     588  Corresponding Source conveyed under this section must be accompanied
     589  by the Installation Information.  But this requirement does not apply
     590  if neither you nor any third party retains the ability to install
     591  modified object code on the User Product (for example, the work has
     592  been installed in ROM).
     593
     594    The requirement to provide Installation Information does not include a
     595  requirement to continue to provide support service, warranty, or updates
     596  for a work that has been modified or installed by the recipient, or for
     597  the User Product in which it has been modified or installed.  Access to a
     598  network may be denied when the modification itself materially and
     599  adversely affects the operation of the network or violates the rules and
     600  protocols for communication across the network.
     601
     602    Corresponding Source conveyed, and Installation Information provided,
     603  in accord with this section must be in a format that is publicly
     604  documented (and with an implementation available to the public in
     605  source code form), and must require no special password or key for
     606  unpacking, reading or copying.
     607
     608    7. Additional Terms.
     609
     610    "Additional permissions" are terms that supplement the terms of this
     611  License by making exceptions from one or more of its conditions.
     612  Additional permissions that are applicable to the entire Program shall
     613  be treated as though they were included in this License, to the extent
     614  that they are valid under applicable law.  If additional permissions
     615  apply only to part of the Program, that part may be used separately
     616  under those permissions, but the entire Program remains governed by
     617  this License without regard to the additional permissions.
     618
     619    When you convey a copy of a covered work, you may at your option
     620  remove any additional permissions from that copy, or from any part of
     621  it.  (Additional permissions may be written to require their own
     622  removal in certain cases when you modify the work.)  You may place
     623  additional permissions on material, added by you to a covered work,
     624  for which you have or can give appropriate copyright permission.
     625
     626    Notwithstanding any other provision of this License, for material you
     627  add to a covered work, you may (if authorized by the copyright holders of
     628  that material) supplement the terms of this License with terms:
     629
     630      a) Disclaiming warranty or limiting liability differently from the
     631      terms of sections 15 and 16 of this License; or
     632
     633      b) Requiring preservation of specified reasonable legal notices or
     634      author attributions in that material or in the Appropriate Legal
     635      Notices displayed by works containing it; or
     636
     637      c) Prohibiting misrepresentation of the origin of that material, or
     638      requiring that modified versions of such material be marked in
     639      reasonable ways as different from the original version; or
     640
     641      d) Limiting the use for publicity purposes of names of licensors or
     642      authors of the material; or
     643
     644      e) Declining to grant rights under trademark law for use of some
     645      trade names, trademarks, or service marks; or
     646
     647      f) Requiring indemnification of licensors and authors of that
     648      material by anyone who conveys the material (or modified versions of
     649      it) with contractual assumptions of liability to the recipient, for
     650      any liability that these contractual assumptions directly impose on
     651      those licensors and authors.
     652
     653    All other non-permissive additional terms are considered "further
     654  restrictions" within the meaning of section 10.  If the Program as you
     655  received it, or any part of it, contains a notice stating that it is
     656  governed by this License along with a term that is a further
     657  restriction, you may remove that term.  If a license document contains
     658  a further restriction but permits relicensing or conveying under this
     659  License, you may add to a covered work material governed by the terms
     660  of that license document, provided that the further restriction does
     661  not survive such relicensing or conveying.
     662
     663    If you add terms to a covered work in accord with this section, you
     664  must place, in the relevant source files, a statement of the
     665  additional terms that apply to those files, or a notice indicating
     666  where to find the applicable terms.
     667
     668    Additional terms, permissive or non-permissive, may be stated in the
     669  form of a separately written license, or stated as exceptions;
     670  the above requirements apply either way.
     671
     672    8. Termination.
     673
     674    You may not propagate or modify a covered work except as expressly
     675  provided under this License.  Any attempt otherwise to propagate or
     676  modify it is void, and will automatically terminate your rights under
     677  this License (including any patent licenses granted under the third
     678  paragraph of section 11).
     679
     680    However, if you cease all violation of this License, then your
     681  license from a particular copyright holder is reinstated (a)
     682  provisionally, unless and until the copyright holder explicitly and
     683  finally terminates your license, and (b) permanently, if the copyright
     684  holder fails to notify you of the violation by some reasonable means
     685  prior to 60 days after the cessation.
     686
     687    Moreover, your license from a particular copyright holder is
     688  reinstated permanently if the copyright holder notifies you of the
     689  violation by some reasonable means, this is the first time you have
     690  received notice of violation of this License (for any work) from that
     691  copyright holder, and you cure the violation prior to 30 days after
     692  your receipt of the notice.
     693
     694    Termination of your rights under this section does not terminate the
     695  licenses of parties who have received copies or rights from you under
     696  this License.  If your rights have been terminated and not permanently
     697  reinstated, you do not qualify to receive new licenses for the same
     698  material under section 10.
     699
     700    9. Acceptance Not Required for Having Copies.
     701
     702    You are not required to accept this License in order to receive or
     703  run a copy of the Program.  Ancillary propagation of a covered work
     704  occurring solely as a consequence of using peer-to-peer transmission
     705  to receive a copy likewise does not require acceptance.  However,
     706  nothing other than this License grants you permission to propagate or
     707  modify any covered work.  These actions infringe copyright if you do
     708  not accept this License.  Therefore, by modifying or propagating a
     709  covered work, you indicate your acceptance of this License to do so.
     710
     711    10. Automatic Licensing of Downstream Recipients.
     712
     713    Each time you convey a covered work, the recipient automatically
     714  receives a license from the original licensors, to run, modify and
     715  propagate that work, subject to this License.  You are not responsible
     716  for enforcing compliance by third parties with this License.
     717
     718    An "entity transaction" is a transaction transferring control of an
     719  organization, or substantially all assets of one, or subdividing an
     720  organization, or merging organizations.  If propagation of a covered
     721  work results from an entity transaction, each party to that
     722  transaction who receives a copy of the work also receives whatever
     723  licenses to the work the party's predecessor in interest had or could
     724  give under the previous paragraph, plus a right to possession of the
     725  Corresponding Source of the work from the predecessor in interest, if
     726  the predecessor has it or can get it with reasonable efforts.
     727
     728    You may not impose any further restrictions on the exercise of the
     729  rights granted or affirmed under this License.  For example, you may
     730  not impose a license fee, royalty, or other charge for exercise of
     731  rights granted under this License, and you may not initiate litigation
     732  (including a cross-claim or counterclaim in a lawsuit) alleging that
     733  any patent claim is infringed by making, using, selling, offering for
     734  sale, or importing the Program or any portion of it.
     735
     736    11. Patents.
     737
     738    A "contributor" is a copyright holder who authorizes use under this
     739  License of the Program or a work on which the Program is based.  The
     740  work thus licensed is called the contributor's "contributor version".
     741
     742    A contributor's "essential patent claims" are all patent claims
     743  owned or controlled by the contributor, whether already acquired or
     744  hereafter acquired, that would be infringed by some manner, permitted
     745  by this License, of making, using, or selling its contributor version,
     746  but do not include claims that would be infringed only as a
     747  consequence of further modification of the contributor version.  For
     748  purposes of this definition, "control" includes the right to grant
     749  patent sublicenses in a manner consistent with the requirements of
     750  this License.
     751
     752    Each contributor grants you a non-exclusive, worldwide, royalty-free
     753  patent license under the contributor's essential patent claims, to
     754  make, use, sell, offer for sale, import and otherwise run, modify and
     755  propagate the contents of its contributor version.
     756
     757    In the following three paragraphs, a "patent license" is any express
     758  agreement or commitment, however denominated, not to enforce a patent
     759  (such as an express permission to practice a patent or covenant not to
     760  sue for patent infringement).  To "grant" such a patent license to a
     761  party means to make such an agreement or commitment not to enforce a
     762  patent against the party.
     763
     764    If you convey a covered work, knowingly relying on a patent license,
     765  and the Corresponding Source of the work is not available for anyone
     766  to copy, free of charge and under the terms of this License, through a
     767  publicly available network server or other readily accessible means,
     768  then you must either (1) cause the Corresponding Source to be so
     769  available, or (2) arrange to deprive yourself of the benefit of the
     770  patent license for this particular work, or (3) arrange, in a manner
     771  consistent with the requirements of this License, to extend the patent
     772  license to downstream recipients.  "Knowingly relying" means you have
     773  actual knowledge that, but for the patent license, your conveying the
     774  covered work in a country, or your recipient's use of the covered work
     775  in a country, would infringe one or more identifiable patents in that
     776  country that you have reason to believe are valid.
     777
     778    If, pursuant to or in connection with a single transaction or
     779  arrangement, you convey, or propagate by procuring conveyance of, a
     780  covered work, and grant a patent license to some of the parties
     781  receiving the covered work authorizing them to use, propagate, modify
     782  or convey a specific copy of the covered work, then the patent license
     783  you grant is automatically extended to all recipients of the covered
     784  work and works based on it.
     785
     786    A patent license is "discriminatory" if it does not include within
     787  the scope of its coverage, prohibits the exercise of, or is
     788  conditioned on the non-exercise of one or more of the rights that are
     789  specifically granted under this License.  You may not convey a covered
     790  work if you are a party to an arrangement with a third party that is
     791  in the business of distributing software, under which you make payment
     792  to the third party based on the extent of your activity of conveying
     793  the work, and under which the third party grants, to any of the
     794  parties who would receive the covered work from you, a discriminatory
     795  patent license (a) in connection with copies of the covered work
     796  conveyed by you (or copies made from those copies), or (b) primarily
     797  for and in connection with specific products or compilations that
     798  contain the covered work, unless you entered into that arrangement,
     799  or that patent license was granted, prior to 28 March 2007.
     800
     801    Nothing in this License shall be construed as excluding or limiting
     802  any implied license or other defenses to infringement that may
     803  otherwise be available to you under applicable patent law.
     804
     805    12. No Surrender of Others' Freedom.
     806
     807    If conditions are imposed on you (whether by court order, agreement or
     808  otherwise) that contradict the conditions of this License, they do not
     809  excuse you from the conditions of this License.  If you cannot convey a
     810  covered work so as to satisfy simultaneously your obligations under this
     811  License and any other pertinent obligations, then as a consequence you may
     812  not convey it at all.  For example, if you agree to terms that obligate you
     813  to collect a royalty for further conveying from those to whom you convey
     814  the Program, the only way you could satisfy both those terms and this
     815  License would be to refrain entirely from conveying the Program.
     816
     817    13. Remote Network Interaction; Use with the GNU General Public License.
     818
     819    Notwithstanding any other provision of this License, if you modify the
     820  Program, your modified version must prominently offer all users
     821  interacting with it remotely through a computer network (if your version
     822  supports such interaction) an opportunity to receive the Corresponding
     823  Source of your version by providing access to the Corresponding Source
     824  from a network server at no charge, through some standard or customary
     825  means of facilitating copying of software.  This Corresponding Source
     826  shall include the Corresponding Source for any work covered by version 3
     827  of the GNU General Public License that is incorporated pursuant to the
     828  following paragraph.
     829
     830    Notwithstanding any other provision of this License, you have
     831  permission to link or combine any covered work with a work licensed
     832  under version 3 of the GNU General Public License into a single
     833  combined work, and to convey the resulting work.  The terms of this
     834  License will continue to apply to the part which is the covered work,
     835  but the work with which it is combined will remain governed by version
     836  3 of the GNU General Public License.
     837
     838    14. Revised Versions of this License.
     839
     840    The Free Software Foundation may publish revised and/or new versions of
     841  the GNU Affero General Public License from time to time.  Such new versions
     842  will be similar in spirit to the present version, but may differ in detail to
     843  address new problems or concerns.
     844
     845    Each version is given a distinguishing version number.  If the
     846  Program specifies that a certain numbered version of the GNU Affero General
     847  Public License "or any later version" applies to it, you have the
     848  option of following the terms and conditions either of that numbered
     849  version or of any later version published by the Free Software
     850  Foundation.  If the Program does not specify a version number of the
     851  GNU Affero General Public License, you may choose any version ever published
     852  by the Free Software Foundation.
     853
     854    If the Program specifies that a proxy can decide which future
     855  versions of the GNU Affero General Public License can be used, that proxy's
     856  public statement of acceptance of a version permanently authorizes you
     857  to choose that version for the Program.
     858
     859    Later license versions may give you additional or different
     860  permissions.  However, no additional obligations are imposed on any
     861  author or copyright holder as a result of your choosing to follow a
     862  later version.
     863
     864    15. Disclaimer of Warranty.
     865
     866    THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
     867  APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
     868  HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
     869  OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
     870  THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
     871  PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
     872  IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
     873  ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
     874
     875    16. Limitation of Liability.
     876
     877    IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
     878  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
     879  THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
     880  GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
     881  USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
     882  DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
     883  PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
     884  EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
     885  SUCH DAMAGES.
     886
     887    17. Interpretation of Sections 15 and 16.
     888
     889    If the disclaimer of warranty and limitation of liability provided
     890  above cannot be given local legal effect according to their terms,
     891  reviewing courts shall apply local law that most closely approximates
     892  an absolute waiver of all civil liability in connection with the
     893  Program, unless a warranty or assumption of liability accompanies a
     894  copy of the Program in return for a fee.
     895
     896                       END OF TERMS AND CONDITIONS
     897
     898              How to Apply These Terms to Your New Programs
     899
     900    If you develop a new program, and you want it to be of the greatest
     901  possible use to the public, the best way to achieve this is to make it
     902  free software which everyone can redistribute and change under these terms.
     903
     904    To do so, attach the following notices to the program.  It is safest
     905  to attach them to the start of each source file to most effectively
     906  state the exclusion of warranty; and each file should have at least
     907  the "copyright" line and a pointer to where the full notice is found.
     908
     909      <one line to give the program's name and a brief idea of what it does.>
     910      Copyright (C) <year>  <name of author>
     911
     912      This program is free software: you can redistribute it and/or modify
     913      it under the terms of the GNU Affero General Public License as published by
     914      the Free Software Foundation, either version 3 of the License, or
     915      (at your option) any later version.
     916
     917      This program is distributed in the hope that it will be useful,
     918      but WITHOUT ANY WARRANTY; without even the implied warranty of
     919      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
     920      GNU Affero General Public License for more details.
     921
     922      You should have received a copy of the GNU Affero General Public License
     923      along with this program.  If not, see <http://www.gnu.org/licenses/>.
     924
     925  Also add information on how to contact you by electronic and paper mail.
     926
     927    If your software can interact with users remotely through a computer
     928  network, you should also make sure that it provides a way for users to
     929  get its source.  For example, if your program is a web application, its
     930  interface could display a "Source" link that leads users to an archive
     931  of the code.  There are many ways you could offer source, and different
     932  solutions will be better for different programs; see section 13 for the
     933  specific requirements.
     934
     935    You should also get your employer (if you work as a programmer) or school,
     936  if any, to sign a "copyright disclaimer" for the program, if necessary.
     937  For more information on this, and how to apply and follow the GNU AGPL, see

     944                         Version 2, June 1991
     945
     946   Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
     947   51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
     948   Everyone is permitted to copy and distribute verbatim copies
     949   of this license document, but changing it is not allowed.
     950
     951                              Preamble
     952
     953    The licenses for most software are designed to take away your
     954  freedom to share and change it.  By contrast, the GNU General Public
     955  License is intended to guarantee your freedom to share and change free
     956  software--to make sure the software is free for all its users.  This
     957  General Public License applies to most of the Free Software
     958  Foundation's software and to any other program whose authors commit to
     959  using it.  (Some other Free Software Foundation software is covered by
     960  the GNU Lesser General Public License instead.)  You can apply it to
     961  your programs, too.
     962
     963    When we speak of free software, we are referring to freedom, not
     964  price.  Our General Public Licenses are designed to make sure that you
     965  have the freedom to distribute copies of free software (and charge for
     966  this service if you wish), that you receive source code or can get it
     967  if you want it, that you can change the software or use pieces of it
     968  in new free programs; and that you know you can do these things.
     969
     970    To protect your rights, we need to make restrictions that forbid
     971  anyone to deny you these rights or to ask you to surrender the rights.
     972  These restrictions translate to certain responsibilities for you if you
     973  distribute copies of the software, or if you modify it.
     974
     975    For example, if you distribute copies of such a program, whether
     976  gratis or for a fee, you must give the recipients all the rights that
     977  you have.  You must make sure that they, too, receive or can get the
     978  source code.  And you must show them these terms so they know their
     979  rights.
     980
     981    We protect your rights with two steps: (1) copyright the software, and
     982  (2) offer you this license which gives you legal permission to copy,
     983  distribute and/or modify the software.
     984
     985    Also, for each author's protection and ours, we want to make certain
     986  that everyone understands that there is no warranty for this free
     987  software.  If the software is modified by someone else and passed on, we
     988  want its recipients to know that what they have is not the original, so
     989  that any problems introduced by others will not reflect on the original
     990  authors' reputations.
     991
     992    Finally, any free program is threatened constantly by software
     993  patents.  We wish to avoid the danger that redistributors of a free
     994  program will individually obtain patent licenses, in effect making the
     995  program proprietary.  To prevent this, we have made it clear that any
     996  patent must be licensed for everyone's free use or not licensed at all.
     997
     998    The precise terms and conditions for copying, distribution and
     999  modification follow.
    1000
    1001                      GNU GENERAL PUBLIC LICENSE
    1002     TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    1003
    1004    0. This License applies to any program or other work which contains
    1005  a notice placed by the copyright holder saying it may be distributed
    1006  under the terms of this General Public License.  The "Program", below,
    1007  refers to any such program or work, and a "work based on the Program"
    1008  means either the Program or any derivative work under copyright law:
    1009  that is to say, a work containing the Program or a portion of it,
    1010  either verbatim or with modifications and/or translated into another
    1011  language.  (Hereinafter, translation is included without limitation in
    1012  the term "modification".)  Each licensee is addressed as "you".
    1013
    1014  Activities other than copying, distribution and modification are not
    1015  covered by this License; they are outside its scope.  The act of
    1016  running the Program is not restricted, and the output from the Program
    1017  is covered only if its contents constitute a work based on the
    1018  Program (independent of having been made by running the Program).
    1019  Whether that is true depends on what the Program does.
    1020
    1021    1. You may copy and distribute verbatim copies of the Program's
    1022  source code as you receive it, in any medium, provided that you
    1023  conspicuously and appropriately publish on each copy an appropriate
    1024  copyright notice and disclaimer of warranty; keep intact all the
    1025  notices that refer to this License and to the absence of any warranty;
    1026  and give any other recipients of the Program a copy of this License
    1027  along with the Program.
    1028
    1029  You may charge a fee for the physical act of transferring a copy, and
    1030  you may at your option offer warranty protection in exchange for a fee.
    1031
    1032    2. You may modify your copy or copies of the Program or any portion
    1033  of it, thus forming a work based on the Program, and copy and
    1034  distribute such modifications or work under the terms of Section 1
    1035  above, provided that you also meet all of these conditions:
    1036
    1037      a) You must cause the modified files to carry prominent notices
    1038      stating that you changed the files and the date of any change.
    1039
    1040      b) You must cause any work that you distribute or publish, that in
    1041      whole or in part contains or is derived from the Program or any
    1042      part thereof, to be licensed as a whole at no charge to all third
    1043      parties under the terms of this License.
    1044
    1045      c) If the modified program normally reads commands interactively
    1046      when run, you must cause it, when started running for such
    1047      interactive use in the most ordinary way, to print or display an
    1048      announcement including an appropriate copyright notice and a
    1049      notice that there is no warranty (or else, saying that you provide
    1050      a warranty) and that users may redistribute the program under
    1051      these conditions, and telling the user how to view a copy of this
    1052      License.  (Exception: if the Program itself is interactive but
    1053      does not normally print such an announcement, your work based on
    1054      the Program is not required to print an announcement.)
    1055
    1056  These requirements apply to the modified work as a whole.  If
    1057  identifiable sections of that work are not derived from the Program,
    1058  and can be reasonably considered independent and separate works in
    1059  themselves, then this License, and its terms, do not apply to those
    1060  sections when you distribute them as separate works.  But when you
    1061  distribute the same sections as part of a whole which is a work based
    1062  on the Program, the distribution of the whole must be on the terms of
    1063  this License, whose permissions for other licensees extend to the
    1064  entire whole, and thus to each and every part regardless of who wrote it.
    1065
    1066  Thus, it is not the intent of this section to claim rights or contest
    1067  your rights to work written entirely by you; rather, the intent is to
    1068  exercise the right to control the distribution of derivative or
    1069  collective works based on the Program.
    1070
    1071  In addition, mere aggregation of another work not based on the Program
    1072  with the Program (or with a work based on the Program) on a volume of
    1073  a storage or distribution medium does not bring the other work under
    1074  the scope of this License.
    1075
    1076    3. You may copy and distribute the Program (or a work based on it,
    1077  under Section 2) in object code or executable form under the terms of
    1078  Sections 1 and 2 above provided that you also do one of the following:
    1079
    1080      a) Accompany it with the complete corresponding machine-readable
    1081      source code, which must be distributed under the terms of Sections
    1082      1 and 2 above on a medium customarily used for software interchange; or,
    1083
    1084      b) Accompany it with a written offer, valid for at least three
    1085      years, to give any third party, for a charge no more than your
    1086      cost of physically performing source distribution, a complete
    1087      machine-readable copy of the corresponding source code, to be
    1088      distributed under the terms of Sections 1 and 2 above on a medium
    1089      customarily used for software interchange; or,
    1090
    1091      c) Accompany it with the information you received as to the offer
    1092      to distribute corresponding source code.  (This alternative is
    1093      allowed only for noncommercial distribution and only if you
    1094      received the program in object code or executable form with such
    1095      an offer, in accord with Subsection b above.)
    1096
    1097  The source code for a work means the preferred form of the work for
    1098  making modifications to it.  For an executable work, complete source
    1099  code means all the source code for all modules it contains, plus any
    1100  associated interface definition files, plus the scripts used to
    1101  control compilation and installation of the executable.  However, as a
    1102  special exception, the source code distributed need not include
    1103  anything that is normally distributed (in either source or binary
    1104  form) with the major components (compiler, kernel, and so on) of the
    1105  operating system on which the executable runs, unless that component
    1106  itself accompanies the executable.
    1107
    1108  If distribution of executable or object code is made by offering
    1109  access to copy from a designated place, then offering equivalent
    1110  access to copy the source code from the same place counts as
    1111  distribution of the source code, even though third parties are not
    1112  compelled to copy the source along with the object code.
    1113
    1114    4. You may not copy, modify, sublicense, or distribute the Program
    1115  except as expressly provided under this License.  Any attempt
    1116  otherwise to copy, modify, sublicense or distribute the Program is
    1117  void, and will automatically terminate your rights under this License.
    1118  However, parties who have received copies, or rights, from you under
    1119  this License will not have their licenses terminated so long as such
    1120  parties remain in full compliance.
    1121
    1122    5. You are not required to accept this License, since you have not
    1123  signed it.  However, nothing else grants you permission to modify or
    1124  distribute the Program or its derivative works.  These actions are
    1125  prohibited by law if you do not accept this License.  Therefore, by
    1126  modifying or distributing the Program (or any work based on the
    1127  Program), you indicate your acceptance of this License to do so, and
    1128  all its terms and conditions for copying, distributing or modifying
    1129  the Program or works based on it.
    1130
    1131    6. Each time you redistribute the Program (or any work based on the
    1132  Program), the recipient automatically receives a license from the
    1133  original licensor to copy, distribute or modify the Program subject to
    1134  these terms and conditions.  You may not impose any further
    1135  restrictions on the recipients' exercise of the rights granted herein.
    1136  You are not responsible for enforcing compliance by third parties to
    1137  this License.
    1138
    1139    7. If, as a consequence of a court judgment or allegation of patent
    1140  infringement or for any other reason (not limited to patent issues),
    1141  conditions are imposed on you (whether by court order, agreement or
    1142  otherwise) that contradict the conditions of this License, they do not
    1143  excuse you from the conditions of this License.  If you cannot
    1144  distribute so as to satisfy simultaneously your obligations under this
    1145  License and any other pertinent obligations, then as a consequence you
    1146  may not distribute the Program at all.  For example, if a patent
    1147  license would not permit royalty-free redistribution of the Program by
    1148  all those who receive copies directly or indirectly through you, then
    1149  the only way you could satisfy both it and this License would be to
    1150  refrain entirely from distribution of the Program.
    1151
    1152  If any portion of this section is held invalid or unenforceable under
    1153  any particular circumstance, the balance of the section is intended to
    1154  apply and the section as a whole is intended to apply in other
    1155  circumstances.
    1156
    1157  It is not the purpose of this section to induce you to infringe any
    1158  patents or other property right claims or to contest validity of any
    1159  such claims; this section has the sole purpose of protecting the
    1160  integrity of the free software distribution system, which is
    1161  implemented by public license practices.  Many people have made
    1162  generous contributions to the wide range of software distributed
    1163  through that system in reliance on consistent application of that
    1164  system; it is up to the author/donor to decide if he or she is willing
    1165  to distribute software through any other system and a licensee cannot
    1166  impose that choice.
    1167
    1168  This section is intended to make thoroughly clear what is believed to
    1169  be a consequence of the rest of this License.
    1170
    1171    8. If the distribution and/or use of the Program is restricted in
    1172  certain countries either by patents or by copyrighted interfaces, the
    1173  original copyright holder who places the Program under this License
    1174  may add an explicit geographical distribution limitation excluding
    1175  those countries, so that distribution is permitted only in or among
    1176  countries not thus excluded.  In such case, this License incorporates
    1177  the limitation as if written in the body of this License.
    1178
    1179    9. The Free Software Foundation may publish revised and/or new versions
    1180  of the General Public License from time to time.  Such new versions will
    1181  be similar in spirit to the present version, but may differ in detail to
    1182  address new problems or concerns.
    1183
    1184  Each version is given a distinguishing version number.  If the Program
    1185  specifies a version number of this License which applies to it and "any
    1186  later version", you have the option of following the terms and conditions
    1187  either of that version or of any later version published by the Free
    1188  Software Foundation.  If the Program does not specify a version number of
    1189  this License, you may choose any version ever published by the Free Software
    1190  Foundation.
    1191
    1192    10. If you wish to incorporate parts of the Program into other free
    1193  programs whose distribution conditions are different, write to the author
    1194  to ask for permission.  For software which is copyrighted by the Free
    1195  Software Foundation, write to the Free Software Foundation; we sometimes
    1196  make exceptions for this.  Our decision will be guided by the two goals
    1197  of preserving the free status of all derivatives of our free software and
    1198  of promoting the sharing and reuse of software generally.
    1199
    1200                              NO WARRANTY
    1201
    1202    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
    1203  FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
    1204  OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
    1205  PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
    1206  OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
    1207  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
    1208  TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
    1209  PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
    1210  REPAIR OR CORRECTION.
    1211
    1212    12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    1213  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
    1214  REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
    1215  INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
    1216  OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
    1217  TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
    1218  YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
    1219  PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
    1220  POSSIBILITY OF SUCH DAMAGES.
    1221
    1222                       END OF TERMS AND CONDITIONS
    1223
    1224              How to Apply These Terms to Your New Programs
    1225
    1226    If you develop a new program, and you want it to be of the greatest
    1227  possible use to the public, the best way to achieve this is to make it
    1228  free software which everyone can redistribute and change under these terms.
    1229
    1230    To do so, attach the following notices to the program.  It is safest
    1231  to attach them to the start of each source file to most effectively
    1232  convey the exclusion of warranty; and each file should have at least
    1233  the "copyright" line and a pointer to where the full notice is found.
    1234
    1235      <one line to give the program's name and a brief idea of what it does.>
    1236      Copyright (C) <year>  <name of author>
    1237
    1238      This program is free software; you can redistribute it and/or modify
    1239      it under the terms of the GNU General Public License as published by
    1240      the Free Software Foundation; either version 2 of the License, or
    1241      (at your option) any later version.
    1242
    1243      This program is distributed in the hope that it will be useful,
    1244      but WITHOUT ANY WARRANTY; without even the implied warranty of
    1245      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    1246      GNU General Public License for more details.
    1247
    1248      You should have received a copy of the GNU General Public License along
    1249      with this program; if not, write to the Free Software Foundation, Inc.,
    1250      51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
    1251
    1252  Also add information on how to contact you by electronic and paper mail.
    1253
    1254  If the program is interactive, make it output a short notice like this
    1255  when it starts in an interactive mode:
    1256
    1257      Gnomovision version 69, Copyright (C) year name of author
    1258      Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    1259      This is free software, and you are welcome to redistribute it
    1260      under certain conditions; type `show c' for details.
    1261
    1262  The hypothetical commands `show w' and `show c' should show the appropriate
    1263  parts of the General Public License.  Of course, the commands you use may
    1264  be called something other than `show w' and `show c'; they could even be
    1265  mouse-clicks or menu items--whatever suits your program.
    1266
    1267  You should also get your employer (if you work as a programmer) or your
    1268  school, if any, to sign a "copyright disclaimer" for the program, if
    1269  necessary.  Here is a sample; alter the names:
    1270
    1271    Yoyodyne, Inc., hereby disclaims all copyright interest in the program
    1272    `Gnomovision' (which makes passes at compilers) written by James Hacker.

    1277  This General Public License does not permit incorporating your program into
    1278  proprietary programs.  If your program is a subroutine library, you may
    1279  consider it more useful to permit linking proprietary applications with the
    1280  library.  If this is what you want to do, use the GNU Lesser General
    1281  Public License instead of this License.

    1288
    1289   Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    1290   Everyone is permitted to copy and distribute verbatim copies
    1291   of this license document, but changing it is not allowed.
    1292
    1293                              Preamble
    1294
    1295    The GNU General Public License is a free, copyleft license for
    1296  software and other kinds of works.
    1297
    1298    The licenses for most software and other practical works are designed
    1299  to take away your freedom to share and change the works.  By contrast,
    1300  the GNU General Public License is intended to guarantee your freedom to
    1301  share and change all versions of a program--to make sure it remains free
    1302  software for all its users.  We, the Free Software Foundation, use the
    1303  GNU General Public License for most of our software; it applies also to
    1304  any other work released this way by its authors.  You can apply it to
    1305  your programs, too.
    1306
    1307    When we speak of free software, we are referring to freedom, not
    1308  price.  Our General Public Licenses are designed to make sure that you
    1309  have the freedom to distribute copies of free software (and charge for
    1310  them if you wish), that you receive source code or can get it if you
    1311  want it, that you can change the software or use pieces of it in new
    1312  free programs, and that you know you can do these things.
    1313
    1314    To protect your rights, we need to prevent others from denying you
    1315  these rights or asking you to surrender the rights.  Therefore, you have
    1316  certain responsibilities if you distribute copies of the software, or if
    1317  you modify it: responsibilities to respect the freedom of others.
    1318
    1319    For example, if you distribute copies of such a program, whether
    1320  gratis or for a fee, you must pass on to the recipients the same
    1321  freedoms that you received.  You must make sure that they, too, receive
    1322  or can get the source code.  And you must show them these terms so they
    1323  know their rights.
    1324
    1325    Developers that use the GNU GPL protect your rights with two steps:
    1326  (1) assert copyright on the software, and (2) offer you this License
    1327  giving you legal permission to copy, distribute and/or modify it.
    1328
    1329    For the developers' and authors' protection, the GPL clearly explains
    1330  that there is no warranty for this free software.  For both users' and
    1331  authors' sake, the GPL requires that modified versions be marked as
    1332  changed, so that their problems will not be attributed erroneously to
    1333  authors of previous versions.
    1334
    1335    Some devices are designed to deny users access to install or run
    1336  modified versions of the software inside them, although the manufacturer
    1337  can do so.  This is fundamentally incompatible with the aim of
    1338  protecting users' freedom to change the software.  The systematic
    1339  pattern of such abuse occurs in the area of products for individuals to
    1340  use, which is precisely where it is most unacceptable.  Therefore, we
    1341  have designed this version of the GPL to prohibit the practice for those
    1342  products.  If such problems arise substantially in other domains, we
    1343  stand ready to extend this provision to those domains in future versions
    1344  of the GPL, as needed to protect the freedom of users.
    1345
    1346    Finally, every program is threatened constantly by software patents.
    1347  States should not allow patents to restrict development and use of
    1348  software on general-purpose computers, but in those that do, we wish to
    1349  avoid the special danger that patents applied to a free program could
    1350  make it effectively proprietary.  To prevent this, the GPL assures that
    1351  patents cannot be used to render the program non-free.
    1352
    1353    The precise terms and conditions for copying, distribution and
    1354  modification follow.
    1355
    1356                         TERMS AND CONDITIONS
    1357
    1358    0. Definitions.
    1359
    1360    "This License" refers to version 3 of the GNU General Public License.
    1361
    1362    "Copyright" also means copyright-like laws that apply to other kinds of
    1363  works, such as semiconductor masks.
    1364
    1365    "The Program" refers to any copyrightable work licensed under this
    1366  License.  Each licensee is addressed as "you".  "Licensees" and
    1367  "recipients" may be individuals or organizations.
    1368
    1369    To "modify" a work means to copy from or adapt all or part of the work
    1370  in a fashion requiring copyright permission, other than the making of an
    1371  exact copy.  The resulting work is called a "modified version" of the
    1372  earlier work or a work "based on" the earlier work.
    1373
    1374    A "covered work" means either the unmodified Program or a work based
    1375  on the Program.
    1376
    1377    To "propagate" a work means to do anything with it that, without
    1378  permission, would make you directly or secondarily liable for
    1379  infringement under applicable copyright law, except executing it on a
    1380  computer or modifying a private copy.  Propagation includes copying,
    1381  distribution (with or without modification), making available to the
    1382  public, and in some countries other activities as well.
    1383
    1384    To "convey" a work means any kind of propagation that enables other
    1385  parties to make or receive copies.  Mere interaction with a user through
    1386  a computer network, with no transfer of a copy, is not conveying.
    1387
    1388    An interactive user interface displays "Appropriate Legal Notices"
    1389  to the extent that it includes a convenient and prominently visible
    1390  feature that (1) displays an appropriate copyright notice, and (2)
    1391  tells the user that there is no warranty for the work (except to the
    1392  extent that warranties are provided), that licensees may convey the
    1393  work under this License, and how to view a copy of this License.  If
    1394  the interface presents a list of user commands or options, such as a
    1395  menu, a prominent item in the list meets this criterion.
    1396
    1397    1. Source Code.
    1398
    1399    The "source code" for a work means the preferred form of the work
    1400  for making modifications to it.  "Object code" means any non-source
    1401  form of a work.
    1402
    1403    A "Standard Interface" means an interface that either is an official
    1404  standard defined by a recognized standards body, or, in the case of
    1405  interfaces specified for a particular programming language, one that
    1406  is widely used among developers working in that language.
    1407
    1408    The "System Libraries" of an executable work include anything, other
    1409  than the work as a whole, that (a) is included in the normal form of
    1410  packaging a Major Component, but which is not part of that Major
    1411  Component, and (b) serves only to enable use of the work with that
    1412  Major Component, or to implement a Standard Interface for which an
    1413  implementation is available to the public in source code form.  A
    1414  "Major Component", in this context, means a major essential component
    1415  (kernel, window system, and so on) of the specific operating system
    1416  (if any) on which the executable work runs, or a compiler used to
    1417  produce the work, or an object code interpreter used to run it.
    1418
    1419    The "Corresponding Source" for a work in object code form means all
    1420  the source code needed to generate, install, and (for an executable
    1421  work) run the object code and to modify the work, including scripts to
    1422  control those activities.  However, it does not include the work's
    1423  System Libraries, or general-purpose tools or generally available free
    1424  programs which are used unmodified in performing those activities but
    1425  which are not part of the work.  For example, Corresponding Source
    1426  includes interface definition files associated with source files for
    1427  the work, and the source code for shared libraries and dynamically
    1428  linked subprograms that the work is specifically designed to require,
    1429  such as by intimate data communication or control flow between those
    1430  subprograms and other parts of the work.
    1431
    1432    The Corresponding Source need not include anything that users
    1433  can regenerate automatically from other parts of the Corresponding
    1434  Source.
    1435
    1436    The Corresponding Source for a work in source code form is that
    1437  same work.
    1438
    1439    2. Basic Permissions.
    1440
    1441    All rights granted under this License are granted for the term of
    1442  copyright on the Program, and are irrevocable provided the stated
    1443  conditions are met.  This License explicitly affirms your unlimited
    1444  permission to run the unmodified Program.  The output from running a
    1445  covered work is covered by this License only if the output, given its
    1446  content, constitutes a covered work.  This License acknowledges your
    1447  rights of fair use or other equivalent, as provided by copyright law.
    1448
    1449    You may make, run and propagate covered works that you do not
    1450  convey, without conditions so long as your license otherwise remains
    1451  in force.  You may convey covered works to others for the sole purpose
    1452  of having them make modifications exclusively for you, or provide you
    1453  with facilities for running those works, provided that you comply with
    1454  the terms of this License in conveying all material for which you do
    1455  not control copyright.  Those thus making or running the covered works
    1456  for you must do so exclusively on your behalf, under your direction
    1457  and control, on terms that prohibit them from making any copies of
    1458  your copyrighted material outside their relationship with you.
    1459
    1460    Conveying under any other circumstances is permitted solely under
    1461  the conditions stated below.  Sublicensing is not allowed; section 10
    1462  makes it unnecessary.
    1463
    1464    3. Protecting Users' Legal Rights From Anti-Circumvention Law.
    1465
    1466    No covered work shall be deemed part of an effective technological
    1467  measure under any applicable law fulfilling obligations under article
    1468  11 of the WIPO copyright treaty adopted on 20 December 1996, or
    1469  similar laws prohibiting or restricting circumvention of such
    1470  measures.
    1471
    1472    When you convey a covered work, you waive any legal power to forbid
    1473  circumvention of technological measures to the extent such circumvention
    1474  is effected by exercising rights under this License with respect to
    1475  the covered work, and you disclaim any intention to limit operation or
    1476  modification of the work as a means of enforcing, against the work's
    1477  users, your or third parties' legal rights to forbid circumvention of
    1478  technological measures.
    1479
    1480    4. Conveying Verbatim Copies.
    1481
    1482    You may convey verbatim copies of the Program's source code as you
    1483  receive it, in any medium, provided that you conspicuously and
    1484  appropriately publish on each copy an appropriate copyright notice;
    1485  keep intact all notices stating that this License and any
    1486  non-permissive terms added in accord with section 7 apply to the code;
    1487  keep intact all notices of the absence of any warranty; and give all
    1488  recipients a copy of this License along with the Program.
    1489
    1490    You may charge any price or no price for each copy that you convey,
    1491  and you may offer support or warranty protection for a fee.
    1492
    1493    5. Conveying Modified Source Versions.
    1494
    1495    You may convey a work based on the Program, or the modifications to
    1496  produce it from the Program, in the form of source code under the
    1497  terms of section 4, provided that you also meet all of these conditions:
    1498
    1499      a) The work must carry prominent notices stating that you modified
    1500      it, and giving a relevant date.
    1501
    1502      b) The work must carry prominent notices stating that it is
    1503      released under this License and any conditions added under section
    1504      7.  This requirement modifies the requirement in section 4 to
    1505      "keep intact all notices".
    1506
    1507      c) You must license the entire work, as a whole, under this
    1508      License to anyone who comes into possession of a copy.  This
    1509      License will therefore apply, along with any applicable section 7
    1510      additional terms, to the whole of the work, and all its parts,
    1511      regardless of how they are packaged.  This License gives no
    1512      permission to license the work in any other way, but it does not
    1513      invalidate such permission if you have separately received it.
    1514
    1515      d) If the work has interactive user interfaces, each must display
    1516      Appropriate Legal Notices; however, if the Program has interactive
    1517      interfaces that do not display Appropriate Legal Notices, your
    1518      work need not make them do so.
    1519
    1520    A compilation of a covered work with other separate and independent
    1521  works, which are not by their nature extensions of the covered work,
    1522  and which are not combined with it such as to form a larger program,
    1523  in or on a volume of a storage or distribution medium, is called an
    1524  "aggregate" if the compilation and its resulting copyright are not
    1525  used to limit the access or legal rights of the compilation's users
    1526  beyond what the individual works permit.  Inclusion of a covered work
    1527  in an aggregate does not cause this License to apply to the other
    1528  parts of the aggregate.
    1529
    1530    6. Conveying Non-Source Forms.
    1531
    1532    You may convey a covered work in object code form under the terms
    1533  of sections 4 and 5, provided that you also convey the
    1534  machine-readable Corresponding Source under the terms of this License,
    1535  in one of these ways:
    1536
    1537      a) Convey the object code in, or embodied in, a physical product
    1538      (including a physical distribution medium), accompanied by the
    1539      Corresponding Source fixed on a durable physical medium
    1540      customarily used for software interchange.
    1541
    1542      b) Convey the object code in, or embodied in, a physical product
    1543      (including a physical distribution medium), accompanied by a
    1544      written offer, valid for at least three years and valid for as
    1545      long as you offer spare parts or customer support for that product
    1546      model, to give anyone who possesses the object code either (1) a
    1547      copy of the Corresponding Source for all the software in the
    1548      product that is covered by this License, on a durable physical
    1549      medium customarily used for software interchange, for a price no
    1550      more than your reasonable cost of physically performing this
    1551      conveying of source, or (2) access to copy the
    1552      Corresponding Source from a network server at no charge.
    1553
    1554      c) Convey individual copies of the object code with a copy of the
    1555      written offer to provide the Corresponding Source.  This
    1556      alternative is allowed only occasionally and noncommercially, and
    1557      only if you received the object code with such an offer, in accord
    1558      with subsection 6b.
    1559
    1560      d) Convey the object code by offering access from a designated
    1561      place (gratis or for a charge), and offer equivalent access to the
    1562      Corresponding Source in the same way through the same place at no
    1563      further charge.  You need not require recipients to copy the
    1564      Corresponding Source along with the object code.  If the place to
    1565      copy the object code is a network server, the Corresponding Source
    1566      may be on a different server (operated by you or a third party)
    1567      that supports equivalent copying facilities, provided you maintain
    1568      clear directions next to the object code saying where to find the
    1569      Corresponding Source.  Regardless of what server hosts the
    1570      Corresponding Source, you remain obligated to ensure that it is
    1571      available for as long as needed to satisfy these requirements.
    1572
    1573      e) Convey the object code using peer-to-peer transmission, provided
    1574      you inform other peers where the object code and Corresponding
    1575      Source of the work are being offered to the general public at no
    1576      charge under subsection 6d.
    1577
    1578    A separable portion of the object code, whose source code is excluded
    1579  from the Corresponding Source as a System Library, need not be
    1580  included in conveying the object code work.
    1581
    1582    A "User Product" is either (1) a "consumer product", which means any
    1583  tangible personal property which is normally used for personal, family,
    1584  or household purposes, or (2) anything designed or sold for incorporation
    1585  into a dwelling.  In determining whether a product is a consumer product,
    1586  doubtful cases shall be resolved in favor of coverage.  For a particular
    1587  product received by a particular user, "normally used" refers to a
    1588  typical or common use of that class of product, regardless of the status
    1589  of the particular user or of the way in which the particular user
    1590  actually uses, or expects or is expected to use, the product.  A product
    1591  is a consumer product regardless of whether the product has substantial
    1592  commercial, industrial or non-consumer uses, unless such uses represent
    1593  the only significant mode of use of the product.
    1594
    1595    "Installation Information" for a User Product means any methods,
    1596  procedures, authorization keys, or other information required to install
    1597  and execute modified versions of a covered work in that User Product from
    1598  a modified version of its Corresponding Source.  The information must
    1599  suffice to ensure that the continued functioning of the modified object
    1600  code is in no case prevented or interfered with solely because
    1601  modification has been made.
    1602
    1603    If you convey an object code work under this section in, or with, or
    1604  specifically for use in, a User Product, and the conveying occurs as
    1605  part of a transaction in which the right of possession and use of the
    1606  User Product is transferred to the recipient in perpetuity or for a
    1607  fixed term (regardless of how the transaction is characterized), the
    1608  Corresponding Source conveyed under this section must be accompanied
    1609  by the Installation Information.  But this requirement does not apply
    1610  if neither you nor any third party retains the ability to install
    1611  modified object code on the User Product (for example, the work has
    1612  been installed in ROM).
    1613
    1614    The requirement to provide Installation Information does not include a
    1615  requirement to continue to provide support service, warranty, or updates
    1616  for a work that has been modified or installed by the recipient, or for
    1617  the User Product in which it has been modified or installed.  Access to a
    1618  network may be denied when the modification itself materially and
    1619  adversely affects the operation of the network or violates the rules and
    1620  protocols for communication across the network.
    1621
    1622    Corresponding Source conveyed, and Installation Information provided,
    1623  in accord with this section must be in a format that is publicly
    1624  documented (and with an implementation available to the public in
    1625  source code form), and must require no special password or key for
    1626  unpacking, reading or copying.
    1627
    1628    7. Additional Terms.
    1629
    1630    "Additional permissions" are terms that supplement the terms of this
    1631  License by making exceptions from one or more of its conditions.
    1632  Additional permissions that are applicable to the entire Program shall
    1633  be treated as though they were included in this License, to the extent
    1634  that they are valid under applicable law.  If additional permissions
    1635  apply only to part of the Program, that part may be used separately
    1636  under those permissions, but the entire Program remains governed by
    1637  this License without regard to the additional permissions.
    1638
    1639    When you convey a copy of a covered work, you may at your option
    1640  remove any additional permissions from that copy, or from any part of
    1641  it.  (Additional permissions may be written to require their own
    1642  removal in certain cases when you modify the work.)  You may place
    1643  additional permissions on material, added by you to a covered work,
    1644  for which you have or can give appropriate copyright permission.
    1645
    1646    Notwithstanding any other provision of this License, for material you
    1647  add to a covered work, you may (if authorized by the copyright holders of
    1648  that material) supplement the terms of this License with terms:
    1649
    1650      a) Disclaiming warranty or limiting liability differently from the
    1651      terms of sections 15 and 16 of this License; or
    1652
    1653      b) Requiring preservation of specified reasonable legal notices or
    1654      author attributions in that material or in the Appropriate Legal
    1655      Notices displayed by works containing it; or
    1656
    1657      c) Prohibiting misrepresentation of the origin of that material, or
    1658      requiring that modified versions of such material be marked in
    1659      reasonable ways as different from the original version; or
    1660
    1661      d) Limiting the use for publicity purposes of names of licensors or
    1662      authors of the material; or
    1663
    1664      e) Declining to grant rights under trademark law for use of some
    1665      trade names, trademarks, or service marks; or
    1666
    1667      f) Requiring indemnification of licensors and authors of that
    1668      material by anyone who conveys the material (or modified versions of
    1669      it) with contractual assumptions of liability to the recipient, for
    1670      any liability that these contractual assumptions directly impose on
    1671      those licensors and authors.
    1672
    1673    All other non-permissive additional terms are considered "further
    1674  restrictions" within the meaning of section 10.  If the Program as you
    1675  received it, or any part of it, contains a notice stating that it is
    1676  governed by this License along with a term that is a further
    1677  restriction, you may remove that term.  If a license document contains
    1678  a further restriction but permits relicensing or conveying under this
    1679  License, you may add to a covered work material governed by the terms
    1680  of that license document, provided that the further restriction does
    1681  not survive such relicensing or conveying.
    1682
    1683    If you add terms to a covered work in accord with this section, you
    1684  must place, in the relevant source files, a statement of the
    1685  additional terms that apply to those files, or a notice indicating
    1686  where to find the applicable terms.
    1687
    1688    Additional terms, permissive or non-permissive, may be stated in the
    1689  form of a separately written license, or stated as exceptions;
    1690  the above requirements apply either way.
    1691
    1692    8. Termination.
    1693
    1694    You may not propagate or modify a covered work except as expressly
    1695  provided under this License.  Any attempt otherwise to propagate or
    1696  modify it is void, and will automatically terminate your rights under
    1697  this License (including any patent licenses granted under the third
    1698  paragraph of section 11).
    1699
    1700    However, if you cease all violation of this License, then your
    1701  license from a particular copyright holder is reinstated (a)
    1702  provisionally, unless and until the copyright holder explicitly and
    1703  finally terminates your license, and (b) permanently, if the copyright
    1704  holder fails to notify you of the violation by some reasonable means
    1705  prior to 60 days after the cessation.
    1706
    1707    Moreover, your license from a particular copyright holder is
    1708  reinstated permanently if the copyright holder notifies you of the
    1709  violation by some reasonable means, this is the first time you have
    1710  received notice of violation of this License (for any work) from that
    1711  copyright holder, and you cure the violation prior to 30 days after
    1712  your receipt of the notice.
    1713
    1714    Termination of your rights under this section does not terminate the
    1715  licenses of parties who have received copies or rights from you under
    1716  this License.  If your rights have been terminated and not permanently
    1717  reinstated, you do not qualify to receive new licenses for the same
    1718  material under section 10.
    1719
    1720    9. Acceptance Not Required for Having Copies.
    1721
    1722    You are not required to accept this License in order to receive or
    1723  run a copy of the Program.  Ancillary propagation of a covered work
    1724  occurring solely as a consequence of using peer-to-peer transmission
    1725  to receive a copy likewise does not require acceptance.  However,
    1726  nothing other than this License grants you permission to propagate or
    1727  modify any covered work.  These actions infringe copyright if you do
    1728  not accept this License.  Therefore, by modifying or propagating a
    1729  covered work, you indicate your acceptance of this License to do so.
    1730
    1731    10. Automatic Licensing of Downstream Recipients.
    1732
    1733    Each time you convey a covered work, the recipient automatically
    1734  receives a license from the original licensors, to run, modify and
    1735  propagate that work, subject to this License.  You are not responsible
    1736  for enforcing compliance by third parties with this License.
    1737
    1738    An "entity transaction" is a transaction transferring control of an
    1739  organization, or substantially all assets of one, or subdividing an
    1740  organization, or merging organizations.  If propagation of a covered
    1741  work results from an entity transaction, each party to that
    1742  transaction who receives a copy of the work also receives whatever
    1743  licenses to the work the party's predecessor in interest had or could
    1744  give under the previous paragraph, plus a right to possession of the
    1745  Corresponding Source of the work from the predecessor in interest, if
    1746  the predecessor has it or can get it with reasonable efforts.
    1747
    1748    You may not impose any further restrictions on the exercise of the
    1749  rights granted or affirmed under this License.  For example, you may
    1750  not impose a license fee, royalty, or other charge for exercise of
    1751  rights granted under this License, and you may not initiate litigation
    1752  (including a cross-claim or counterclaim in a lawsuit) alleging that
    1753  any patent claim is infringed by making, using, selling, offering for
    1754  sale, or importing the Program or any portion of it.
    1755
    1756    11. Patents.
    1757
    1758    A "contributor" is a copyright holder who authorizes use under this
    1759  License of the Program or a work on which the Program is based.  The
    1760  work thus licensed is called the contributor's "contributor version".
    1761
    1762    A contributor's "essential patent claims" are all patent claims
    1763  owned or controlled by the contributor, whether already acquired or
    1764  hereafter acquired, that would be infringed by some manner, permitted
    1765  by this License, of making, using, or selling its contributor version,
    1766  but do not include claims that would be infringed only as a
    1767  consequence of further modification of the contributor version.  For
    1768  purposes of this definition, "control" includes the right to grant
    1769  patent sublicenses in a manner consistent with the requirements of
    1770  this License.
    1771
    1772    Each contributor grants you a non-exclusive, worldwide, royalty-free
    1773  patent license under the contributor's essential patent claims, to
    1774  make, use, sell, offer for sale, import and otherwise run, modify and
    1775  propagate the contents of its contributor version.
    1776
    1777    In the following three paragraphs, a "patent license" is any express
    1778  agreement or commitment, however denominated, not to enforce a patent
    1779  (such as an express permission to practice a patent or covenant not to
    1780  sue for patent infringement).  To "grant" such a patent license to a
    1781  party means to make such an agreement or commitment not to enforce a
    1782  patent against the party.
    1783
    1784    If you convey a covered work, knowingly relying on a patent license,
    1785  and the Corresponding Source of the work is not available for anyone
    1786  to copy, free of charge and under the terms of this License, through a
    1787  publicly available network server or other readily accessible means,
    1788  then you must either (1) cause the Corresponding Source to be so
    1789  available, or (2) arrange to deprive yourself of the benefit of the
    1790  patent license for this particular work, or (3) arrange, in a manner
    1791  consistent with the requirements of this License, to extend the patent
    1792  license to downstream recipients.  "Knowingly relying" means you have
    1793  actual knowledge that, but for the patent license, your conveying the
    1794  covered work in a country, or your recipient's use of the covered work
    1795  in a country, would infringe one or more identifiable patents in that
    1796  country that you have reason to believe are valid.
    1797
    1798    If, pursuant to or in connection with a single transaction or
    1799  arrangement, you convey, or propagate by procuring conveyance of, a
    1800  covered work, and grant a patent license to some of the parties
    1801  receiving the covered work authorizing them to use, propagate, modify
    1802  or convey a specific copy of the covered work, then the patent license
    1803  you grant is automatically extended to all recipients of the covered
    1804  work and works based on it.
    1805
    1806    A patent license is "discriminatory" if it does not include within
    1807  the scope of its coverage, prohibits the exercise of, or is
    1808  conditioned on the non-exercise of one or more of the rights that are
    1809  specifically granted under this License.  You may not convey a covered
    1810  work if you are a party to an arrangement with a third party that is
    1811  in the business of distributing software, under which you make payment
    1812  to the third party based on the extent of your activity of conveying
    1813  the work, and under which the third party grants, to any of the
    1814  parties who would receive the covered work from you, a discriminatory
    1815  patent license (a) in connection with copies of the covered work
    1816  conveyed by you (or copies made from those copies), or (b) primarily
    1817  for and in connection with specific products or compilations that
    1818  contain the covered work, unless you entered into that arrangement,
    1819  or that patent license was granted, prior to 28 March 2007.
    1820
    1821    Nothing in this License shall be construed as excluding or limiting
    1822  any implied license or other defenses to infringement that may
    1823  otherwise be available to you under applicable patent law.
    1824
    1825    12. No Surrender of Others' Freedom.
    1826
    1827    If conditions are imposed on you (whether by court order, agreement or
    1828  otherwise) that contradict the conditions of this License, they do not
    1829  excuse you from the conditions of this License.  If you cannot convey a
    1830  covered work so as to satisfy simultaneously your obligations under this
    1831  License and any other pertinent obligations, then as a consequence you may
    1832  not convey it at all.  For example, if you agree to terms that obligate you
    1833  to collect a royalty for further conveying from those to whom you convey
    1834  the Program, the only way you could satisfy both those terms and this
    1835  License would be to refrain entirely from conveying the Program.
    1836
    1837    13. Use with the GNU Affero General Public License.
    1838
    1839    Notwithstanding any other provision of this License, you have
    1840  permission to link or combine any covered work with a work licensed
    1841  under version 3 of the GNU Affero General Public License into a single
    1842  combined work, and to convey the resulting work.  The terms of this
    1843  License will continue to apply to the part which is the covered work,
    1844  but the special requirements of the GNU Affero General Public License,
    1845  section 13, concerning interaction through a network will apply to the
    1846  combination as such.
    1847
    1848    14. Revised Versions of this License.
    1849
    1850    The Free Software Foundation may publish revised and/or new versions of
    1851  the GNU General Public License from time to time.  Such new versions will
    1852  be similar in spirit to the present version, but may differ in detail to
    1853  address new problems or concerns.
    1854
    1855    Each version is given a distinguishing version number.  If the
    1856  Program specifies that a certain numbered version of the GNU General
    1857  Public License "or any later version" applies to it, you have the
    1858  option of following the terms and conditions either of that numbered
    1859  version or of any later version published by the Free Software
    1860  Foundation.  If the Program does not specify a version number of the
    1861  GNU General Public License, you may choose any version ever published
    1862  by the Free Software Foundation.
    1863
    1864    If the Program specifies that a proxy can decide which future
    1865  versions of the GNU General Public License can be used, that proxy's
    1866  public statement of acceptance of a version permanently authorizes you
    1867  to choose that version for the Program.
    1868
    1869    Later license versions may give you additional or different
    1870  permissions.  However, no additional obligations are imposed on any
    1871  author or copyright holder as a result of your choosing to follow a
    1872  later version.
    1873
    1874    15. Disclaimer of Warranty.
    1875
    1876    THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
    1877  APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
    1878  HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
    1879  OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
    1880  THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
    1881  PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
    1882  IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
    1883  ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    1884
    1885    16. Limitation of Liability.
    1886
    1887    IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    1888  WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
    1889  THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
    1890  GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
    1891  USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
    1892  DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
    1893  PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
    1894  EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
    1895  SUCH DAMAGES.
    1896
    1897    17. Interpretation of Sections 15 and 16.
    1898
    1899    If the disclaimer of warranty and limitation of liability provided
    1900  above cannot be given local legal effect according to their terms,
    1901  reviewing courts shall apply local law that most closely approximates
    1902  an absolute waiver of all civil liability in connection with the
    1903  Program, unless a warranty or assumption of liability accompanies a
    1904  copy of the Program in return for a fee.
    1905
    1906                       END OF TERMS AND CONDITIONS
    1907
    1908              How to Apply These Terms to Your New Programs
    1909
    1910    If you develop a new program, and you want it to be of the greatest
    1911  possible use to the public, the best way to achieve this is to make it
    1912  free software which everyone can redistribute and change under these terms.
    1913
    1914    To do so, attach the following notices to the program.  It is safest
    1915  to attach them to the start of each source file to most effectively
    1916  state the exclusion of warranty; and each file should have at least
    1917  the "copyright" line and a pointer to where the full notice is found.
    1918
    1919      <one line to give the program's name and a brief idea of what it does.>
    1920      Copyright (C) <year>  <name of author>
    1921
    1922      This program is free software: you can redistribute it and/or modify
    1923      it under the terms of the GNU General Public License as published by
    1924      the Free Software Foundation, either version 3 of the License, or
    1925      (at your option) any later version.
    1926
    1927      This program is distributed in the hope that it will be useful,
    1928      but WITHOUT ANY WARRANTY; without even the implied warranty of
    1929      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    1930      GNU General Public License for more details.
    1931
    1932      You should have received a copy of the GNU General Public License
    1933      along with this program.  If not, see <http://www.gnu.org/licenses/>.
    1934
    1935  Also add information on how to contact you by electronic and paper mail.
    1936
    1937    If the program does terminal interaction, make it output a short
    1938  notice like this when it starts in an interactive mode:
    1939
    1940      <program>  Copyright (C) <year>  <name of author>
    1941      This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    1942      This is free software, and you are welcome to redistribute it
    1943      under certain conditions; type `show c' for details.
    1944
    1945  The hypothetical commands `show w' and `show c' should show the appropriate
    1946  parts of the General Public License.  Of course, your program's commands
    1947  might be different; for a GUI interface, you would use an "about box".
    1948
    1949    You should also get your employer (if you work as a programmer) or school,
    1950  if any, to sign a "copyright disclaimer" for the program, if necessary.
    1951  For more information on this, and how to apply and follow the GNU GPL, see
    1952  <http://www.gnu.org/licenses/>.
    1953
    1954    The GNU General Public License does not permit incorporating your program
    1955  into proprietary programs.  If your program is a subroutine library, you
    1956  may consider it more useful to permit linking proprietary applications with
    1957  the library.  If this is what you want to do, use the GNU Lesser General
    1958  Public License instead of this License.  But first, please read
    1959  <http://www.gnu.org/philosophy/why-not-lgpl.html>.

    1969   Everyone is permitted to copy and distribute verbatim copies
    1970   of this license document, but changing it is not allowed.
    1971
    1972  [This is the first released version of the Lesser GPL.  It also counts
    1973   as the successor of the GNU Library Public License, version 2, hence
    1974   the version number 2.1.]
    1975
    1976                              Preamble
    1977
    1978    The licenses for most software are designed to take away your
    1979  freedom to share and change it.  By contrast, the GNU General Public
    1980  Licenses are intended to guarantee your freedom to share and change
    1981  free software--to make sure the software is free for all its users.
    1982
    1983    This license, the Lesser General Public License, applies to some
    1984  specially designated software packages--typically libraries--of the
    1985  Free Software Foundation and other authors who decide to use it.  You
    1986  can use it too, but we suggest you first think carefully about whether
    1987  this license or the ordinary General Public License is the better
    1988  strategy to use in any particular case, based on the explanations below.
    1989
    1990    When we speak of free software, we are referring to freedom of use,
    1991  not price.  Our General Public Licenses are designed to make sure that
    1992  you have the freedom to distribute copies of free software (and charge
    1993  for this service if you wish); that you receive source code or can get
    1994  it if you want it; that you can change the software and use pieces of
    1995  it in new free programs; and that you are informed that you can do
    1996  these things.
    1997
    1998    To protect your rights, we need to make restrictions that forbid
    1999  distributors to deny you these rights or to ask you to surrender these
    2000  rights.  These restrictions translate to certain responsibilities for
    2001  you if you distribute copies of the library or if you modify it.
    2002
    2003    For example, if you distribute copies of the library, whether gratis
    2004  or for a fee, you must give the recipients all the rights that we gave
    2005  you.  You must make sure that they, too, receive or can get the source
    2006  code.  If you link other code with the library, you must provide
    2007  complete object files to the recipients, so that they can relink them
    2008  with the library after making changes to the library and recompiling
    2009  it.  And you must show them these terms so they know their rights.
    2010
    2011    We protect your rights with a two-step method: (1) we copyright the
    2012  library, and (2) we offer you this license, which gives you legal
    2013  permission to copy, distribute and/or modify the library.
    2014
    2015    To protect each distributor, we want to make it very clear that
    2016  there is no warranty for the free library.  Also, if the library is
    2017  modified by someone else and passed on, the recipients should know
    2018  that what they have is not the original version, so that the original
    2019  author's reputation will not be affected by problems that might be
    2020  introduced by others.
    2021
    2022    Finally, software patents pose a constant threat to the existence of
    2023  any free program.  We wish to make sure that a company cannot
    2024  effectively restrict the users of a free program by obtaining a
    2025  restrictive license from a patent holder.  Therefore, we insist that
    2026  any patent license obtained for a version of the library must be
    2027  consistent with the full freedom of use specified in this license.
    2028
    2029    Most GNU software, including some libraries, is covered by the
    2030  ordinary GNU General Public License.  This license, the GNU Lesser
    2031  General Public License, applies to certain designated libraries, and
    2032  is quite different from the ordinary General Public License.  We use
    2033  this license for certain libraries in order to permit linking those
    2034  libraries into non-free programs.
    2035
    2036    When a program is linked with a library, whether statically or using
    2037  a shared library, the combination of the two is legally speaking a
    2038  combined work, a derivative of the original library.  The ordinary
    2039  General Public License therefore permits such linking only if the
    2040  entire combination fits its criteria of freedom.  The Lesser General
    2041  Public License permits more lax criteria for linking other code with
    2042  the library.
    2043
    2044    We call this license the "Lesser" General Public License because it
    2045  does Less to protect the user's freedom than the ordinary General
    2046  Public License.  It also provides other free software developers Less
    2047  of an advantage over competing non-free programs.  These disadvantages
    2048  are the reason we use the ordinary General Public License for many
    2049  libraries.  However, the Lesser license provides advantages in certain
    2050  special circumstances.
    2051
    2052    For example, on rare occasions, there may be a special need to
    2053  encourage the widest possible use of a certain library, so that it becomes
    2054  a de-facto standard.  To achieve this, non-free programs must be
    2055  allowed to use the library.  A more frequent case is that a free
    2056  library does the same job as widely used non-free libraries.  In this
    2057  case, there is little to gain by limiting the free library to free
    2058  software only, so we use the Lesser General Public License.
    2059
    2060    In other cases, permission to use a particular library in non-free
    2061  programs enables a greater number of people to use a large body of
    2062  free software.  For example, permission to use the GNU C Library in
    2063  non-free programs enables many more people to use the whole GNU
    2064  operating system, as well as its variant, the GNU/Linux operating
    2065  system.
    2066
    2067    Although the Lesser General Public License is Less protective of the
    2068  users' freedom, it does ensure that the user of a program that is
    2069  linked with the Library has the freedom and the wherewithal to run
    2070  that program using a modified version of the Library.
    2071
    2072    The precise terms and conditions for copying, distribution and
    2073  modification follow.  Pay close attention to the difference between a
    2074  "work based on the library" and a "work that uses the library".  The
    2075  former contains code derived from the library, whereas the latter must
    2076  be combined with the library in order to run.
    2077
    2078                    GNU LESSER GENERAL PUBLIC LICENSE
    2079     TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
    2080
    2081    0. This License Agreement applies to any software library or other
    2082  program which contains a notice placed by the copyright holder or
    2083  other authorized party saying it may be distributed under the terms of
    2084  this Lesser General Public License (also called "this License").
    2085  Each licensee is addressed as "you".
    2086
    2087    A "library" means a collection of software functions and/or data
    2088  prepared so as to be conveniently linked with application programs
    2089  (which use some of those functions and data) to form executables.
    2090
    2091    The "Library", below, refers to any such software library or work
    2092  which has been distributed under these terms.  A "work based on the
    2093  Library" means either the Library or any derivative work under
    2094  copyright law: that is to say, a work containing the Library or a
    2095  portion of it, either verbatim or with modifications and/or translated
    2096  straightforwardly into another language.  (Hereinafter, translation is
    2097  included without limitation in the term "modification".)
    2098
    2099    "Source code" for a work means the preferred form of the work for
    2100  making modifications to it.  For a library, complete source code means
    2101  all the source code for all modules it contains, plus any associated
    2102  interface definition files, plus the scripts used to control compilation
    2103  and installation of the library.
    2104
    2105    Activities other than copying, distribution and modification are not
    2106  covered by this License; they are outside its scope.  The act of
    2107  running a program using the Library is not restricted, and output from
    2108  such a program is covered only if its contents constitute a work based
    2109  on the Library (independent of the use of the Library in a tool for
    2110  writing it).  Whether that is true depends on what the Library does
    2111  and what the program that uses the Library does.
    2112
    2113    1. You may copy and distribute verbatim copies of the Library's
    2114  complete source code as you receive it, in any medium, provided that
    2115  you conspicuously and appropriately publish on each copy an
    2116  appropriate copyright notice and disclaimer of warranty; keep intact
    2117  all the notices that refer to this License and to the absence of any
    2118  warranty; and distribute a copy of this License along with the
    2119  Library.
    2120
    2121    You may charge a fee for the physical act of transferring a copy,
    2122  and you may at your option offer warranty protection in exchange for a
    2123  fee.
    2124
    2125    2. You may modify your copy or copies of the Library or any portion
    2126  of it, thus forming a work based on the Library, and copy and
    2127  distribute such modifications or work under the terms of Section 1
    2128  above, provided that you also meet all of these conditions:
    2129
    2130      a) The modified work must itself be a software library.
    2131
    2132      b) You must cause the files modified to carry prominent notices
    2133      stating that you changed the files and the date of any change.
    2134
    2135      c) You must cause the whole of the work to be licensed at no
    2136      charge to all third parties under the terms of this License.
    2137
    2138      d) If a facility in the modified Library refers to a function or a
    2139      table of data to be supplied by an application program that uses
    2140      the facility, other than as an argument passed when the facility
    2141      is invoked, then you must make a good faith effort to ensure that,
    2142      in the event an application does not supply such function or
    2143      table, the facility still operates, and performs whatever part of
    2144      its purpose remains meaningful.
    2145
    2146      (For example, a function in a library to compute square roots has
    2147      a purpose that is entirely well-defined independent of the
    2148      application.  Therefore, Subsection 2d requires that any
    2149      application-supplied function or table used by this function must
    2150      be optional: if the application does not supply it, the square
    2151      root function must still compute square roots.)
    2152
    2153  These requirements apply to the modified work as a whole.  If
    2154  identifiable sections of that work are not derived from the Library,
    2155  and can be reasonably considered independent and separate works in
    2156  themselves, then this License, and its terms, do not apply to those
    2157  sections when you distribute them as separate works.  But when you
    2158  distribute the same sections as part of a whole which is a work based
    2159  on the Library, the distribution of the whole must be on the terms of
    2160  this License, whose permissions for other licensees extend to the
    2161  entire whole, and thus to each and every part regardless of who wrote
    2162  it.
    2163
    2164  Thus, it is not the intent of this section to claim rights or contest
    2165  your rights to work written entirely by you; rather, the intent is to
    2166  exercise the right to control the distribution of derivative or
    2167  collective works based on the Library.
    2168
    2169  In addition, mere aggregation of another work not based on the Library
    2170  with the Library (or with a work based on the Library) on a volume of
    2171  a storage or distribution medium does not bring the other work under
    2172  the scope of this License.
    2173
    2174    3. You may opt to apply the terms of the ordinary GNU General Public
    2175  License instead of this License to a given copy of the Library.  To do
    2176  this, you must alter all the notices that refer to this License, so
    2177  that they refer to the ordinary GNU General Public License, version 2,
    2178  instead of to this License.  (If a newer version than version 2 of the
    2179  ordinary GNU General Public License has appeared, then you can specify
    2180  that version instead if you wish.)  Do not make any other change in
    2181  these notices.
    2182
    2183    Once this change is made in a given copy, it is irreversible for
    2184  that copy, so the ordinary GNU General Public License applies to all
    2185  subsequent copies and derivative works made from that copy.
    2186
    2187    This option is useful when you wish to copy part of the code of
    2188  the Library into a program that is not a library.
    2189
    2190    4. You may copy and distribute the Library (or a portion or
    2191  derivative of it, under Section 2) in object code or executable form
    2192  under the terms of Sections 1 and 2 above provided that you accompany
    2193  it with the complete corresponding machine-readable source code, which
    2194  must be distributed under the terms of Sections 1 and 2 above on a
    2195  medium customarily used for software interchange.
    2196
    2197    If distribution of object code is made by offering access to copy
    2198  from a designated place, then offering equivalent access to copy the
    2199  source code from the same place satisfies the requirement to
    2200  distribute the source code, even though third parties are not
    2201  compelled to copy the source along with the object code.
    2202
    2203    5. A program that contains no derivative of any portion of the
    2204  Library, but is designed to work with the Library by being compiled or
    2205  linked with it, is called a "work that uses the Library".  Such a
    2206  work, in isolation, is not a derivative work of the Library, and
    2207  therefore falls outside the scope of this License.
    2208
    2209    However, linking a "work that uses the Library" with the Library
    2210  creates an executable that is a derivative of the Library (because it
    2211  contains portions of the Library), rather than a "work that uses the
    2212  library".  The executable is therefore covered by this License.
    2213  Section 6 states terms for distribution of such executables.
    2214
    2215    When a "work that uses the Library" uses material from a header file
    2216  that is part of the Library, the object code for the work may be a
    2217  derivative work of the Library even though the source code is not.
    2218  Whether this is true is especially significant if the work can be
    2219  linked without the Library, or if the work is itself a library.  The
    2220  threshold for this to be true is not precisely defined by law.
    2221
    2222    If such an object file uses only numerical parameters, data
    2223  structure layouts and accessors, and small macros and small inline
    2224  functions (ten lines or less in length), then the use of the object
    2225  file is unrestricted, regardless of whether it is legally a derivative
    2226  work.  (Executables containing this object code plus portions of the
    2227  Library will still fall under Section 6.)
    2228
    2229    Otherwise, if the work is a derivative of the Library, you may
    2230  distribute the object code for the work under the terms of Section 6.
    2231  Any executables containing that work also fall under Section 6,
    2232  whether or not they are linked directly with the Library itself.
    2233
    2234    6. As an exception to the Sections above, you may also combine or
    2235  link a "work that uses the Library" with the Library to produce a
    2236  work containing portions of the Library, and distribute that work
    2237  under terms of your choice, provided that the terms permit
    2238  modification of the work for the customer's own use and reverse
    2239  engineering for debugging such modifications.
    2240
    2241    You must give prominent notice with each copy of the work that the
    2242  Library is used in it and that the Library and its use are covered by
    2243  this License.  You must supply a copy of this License.  If the work
    2244  during execution displays copyright notices, you must include the
    2245  copyright notice for the Library among them, as well as a reference
    2246  directing the user to the copy of this License.  Also, you must do one
    2247  of these things:
    2248
    2249      a) Accompany the work with the complete corresponding
    2250      machine-readable source code for the Library including whatever
    2251      changes were used in the work (which must be distributed under
    2252      Sections 1 and 2 above); and, if the work is an executable linked
    2253      with the Library, with the complete machine-readable "work that
    2254      uses the Library", as object code and/or source code, so that the
    2255      user can modify the Library and then relink to produce a modified
    2256      executable containing the modified Library.  (It is understood
    2257      that the user who changes the contents of definitions files in the
    2258      Library will not necessarily be able to recompile the application
    2259      to use the modified definitions.)
    2260
    2261      b) Use a suitable shared library mechanism for linking with the
    2262      Library.  A suitable mechanism is one that (1) uses at run time a
    2263      copy of the library already present on the user's computer system,
    2264      rather than copying library functions into the executable, and (2)
    2265      will operate properly with a modified version of the library, if
    2266      the user installs one, as long as the modified version is
    2267      interface-compatible with the version that the work was made with.
    2268
    2269      c) Accompany the work with a written offer, valid for at
    2270      least three years, to give the same user the materials
    2271      specified in Subsection 6a, above, for a charge no more
    2272      than the cost of performing this distribution.
    2273
    2274      d) If distribution of the work is made by offering access to copy
    2275      from a designated place, offer equivalent access to copy the above
    2276      specified materials from the same place.
    2277
    2278      e) Verify that the user has already received a copy of these
    2279      materials or that you have already sent this user a copy.
    2280
    2281    For an executable, the required form of the "work that uses the
    2282  Library" must include any data and utility programs needed for
    2283  reproducing the executable from it.  However, as a special exception,
    2284  the materials to be distributed need not include anything that is
    2285  normally distributed (in either source or binary form) with the major
    2286  components (compiler, kernel, and so on) of the operating system on
    2287  which the executable runs, unless that component itself accompanies
    2288  the executable.
    2289
    2290    It may happen that this requirement contradicts the license
    2291  restrictions of other proprietary libraries that do not normally
    2292  accompany the operating system.  Such a contradiction means you cannot
    2293  use both them and the Library together in an executable that you
    2294  distribute.
    2295
    2296    7. You may place library facilities that are a work based on the
    2297  Library side-by-side in a single library together with other library
    2298  facilities not covered by this License, and distribute such a combined
    2299  library, provided that the separate distribution of the work based on
    2300  the Library and of the other library facilities is otherwise
    2301  permitted, and provided that you do these two things:
    2302
    2303      a) Accompany the combined library with a copy of the same work
    2304      based on the Library, uncombined with any other library
    2305      facilities.  This must be distributed under the terms of the
    2306      Sections above.
    2307
    2308      b) Give prominent notice with the combined library of the fact
    2309      that part of it is a work based on the Library, and explaining
    2310      where to find the accompanying uncombined form of the same work.
    2311
    2312    8. You may not copy, modify, sublicense, link with, or distribute
    2313  the Library except as expressly provided under this License.  Any
    2314  attempt otherwise to copy, modify, sublicense, link with, or
    2315  distribute the Library is void, and will automatically terminate your
    2316  rights under this License.  However, parties who have received copies,
    2317  or rights, from you under this License will not have their licenses
    2318  terminated so long as such parties remain in full compliance.
    2319
    2320    9. You are not required to accept this License, since you have not
    2321  signed it.  However, nothing else grants you permission to modify or
    2322  distribute the Library or its derivative works.  These actions are
    2323  prohibited by law if you do not accept this License.  Therefore, by
    2324  modifying or distributing the Library (or any work based on the
    2325  Library), you indicate your acceptance of this License to do so, and
    2326  all its terms and conditions for copying, distributing or modifying
    2327  the Library or works based on it.
    2328
    2329    10. Each time you redistribute the Library (or any work based on the
    2330  Library), the recipient automatically receives a license from the
    2331  original licensor to copy, distribute, link with or modify the Library
    2332  subject to these terms and conditions.  You may not impose any further
    2333  restrictions on the recipients' exercise of the rights granted herein.
    2334  You are not responsible for enforcing compliance by third parties with
    2335  this License.
    2336
    2337    11. If, as a consequence of a court judgment or allegation of patent
    2338  infringement or for any other reason (not limited to patent issues),
    2339  conditions are imposed on you (whether by court order, agreement or
    2340  otherwise) that contradict the conditions of this License, they do not
    2341  excuse you from the conditions of this License.  If you cannot
    2342  distribute so as to satisfy simultaneously your obligations under this
    2343  License and any other pertinent obligations, then as a consequence you
    2344  may not distribute the Library at all.  For example, if a patent
    2345  license would not permit royalty-free redistribution of the Library by
    2346  all those who receive copies directly or indirectly through you, then
    2347  the only way you could satisfy both it and this License would be to
    2348  refrain entirely from distribution of the Library.
    2349
    2350  If any portion of this section is held invalid or unenforceable under any
    2351  particular circumstance, the balance of the section is intended to apply,
    2352  and the section as a whole is intended to apply in other circumstances.
    2353
    2354  It is not the purpose of this section to induce you to infringe any
    2355  patents or other property right claims or to contest validity of any
    2356  such claims; this section has the sole purpose of protecting the
    2357  integrity of the free software distribution system which is
    2358  implemented by public license practices.  Many people have made
    2359  generous contributions to the wide range of software distributed
    2360  through that system in reliance on consistent application of that
    2361  system; it is up to the author/donor to decide if he or she is willing
    2362  to distribute software through any other system and a licensee cannot
    2363  impose that choice.
    2364
    2365  This section is intended to make thoroughly clear what is believed to
    2366  be a consequence of the rest of this License.
    2367
    2368    12. If the distribution and/or use of the Library is restricted in
    2369  certain countries either by patents or by copyrighted interfaces, the
    2370  original copyright holder who places the Library under this License may add
    2371  an explicit geographical distribution limitation excluding those countries,
    2372  so that distribution is permitted only in or among countries not thus
    2373  excluded.  In such case, this License incorporates the limitation as if
    2374  written in the body of this License.
    2375
    2376    13. The Free Software Foundation may publish revised and/or new
    2377  versions of the Lesser General Public License from time to time.
    2378  Such new versions will be similar in spirit to the present version,
    2379  but may differ in detail to address new problems or concerns.
    2380
    2381  Each version is given a distinguishing version number.  If the Library
    2382  specifies a version number of this License which applies to it and
    2383  "any later version", you have the option of following the terms and
    2384  conditions either of that version or of any later version published by
    2385  the Free Software Foundation.  If the Library does not specify a
    2386  license version number, you may choose any version ever published by
    2387  the Free Software Foundation.
    2388
    2389    14. If you wish to incorporate parts of the Library into other free
    2390  programs whose distribution conditions are incompatible with these,
    2391  write to the author to ask for permission.  For software which is
    2392  copyrighted by the Free Software Foundation, write to the Free
    2393  Software Foundation; we sometimes make exceptions for this.  Our
    2394  decision will be guided by the two goals of preserving the free status
    2395  of all derivatives of our free software and of promoting the sharing
    2396  and reuse of software generally.
    2397
    2398                              NO WARRANTY
    2399
    2400    15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
    2401  WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
    2402  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
    2403  OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
    2404  KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
    2405  IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
    2406  PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
    2407  LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
    2408  THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    2409
    2410    16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
    2411  WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
    2412  AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
    2413  FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
    2414  CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
    2415  LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
    2416  RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
    2417  FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
    2418  SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
    2419  DAMAGES.
    2420
    2421                       END OF TERMS AND CONDITIONS
    2422
    2423             How to Apply These Terms to Your New Libraries
    2424
    2425    If you develop a new library, and you want it to be of the greatest
    2426  possible use to the public, we recommend making it free software that
    2427  everyone can redistribute and change.  You can do so by permitting
    2428  redistribution under these terms (or, alternatively, under the terms of the
    2429  ordinary General Public License).
    2430
    2431    To apply these terms, attach the following notices to the library.  It is
    2432  safest to attach them to the start of each source file to most effectively
    2433  convey the exclusion of warranty; and each file should have at least the
    2434  "copyright" line and a pointer to where the full notice is found.
    2435
    2436      <one line to give the library's name and a brief idea of what it does.>

    2438
    2439      This library is free software; you can redistribute it and/or
    2440      modify it under the terms of the GNU Lesser General Public
    2441      License as published by the Free Software Foundation; either
    2442      version 2.1 of the License, or (at your option) any later version.
    2443
    2444      This library is distributed in the hope that it will be useful,
    2445      but WITHOUT ANY WARRANTY; without even the implied warranty of
    2446      MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
    2447      Lesser General Public License for more details.
    2448
    2449      You should have received a copy of the GNU Lesser General Public
    2450      License along with this library; if not, write to the Free Software

    2452
    2453  Also add information on how to contact you by electronic and paper mail.
    2454
    2455  You should also get your employer (if you work as a programmer) or your
    2456  school, if any, to sign a "copyright disclaimer" for the library, if
    2457  necessary.  Here is a sample; alter the names:

    2472
    2473   Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
    2474   Everyone is permitted to copy and distribute verbatim copies
    2475   of this license document, but changing it is not allowed.
    2476
    2477
    2478    This version of the GNU Lesser General Public License incorporates
    2479  the terms and conditions of version 3 of the GNU General Public
    2480  License, supplemented by the additional permissions listed below.
    2481
    2482    0. Additional Definitions.
    2483
    2484    As used herein, "this License" refers to version 3 of the GNU Lesser
    2485  General Public License, and the "GNU GPL" refers to version 3 of the GNU
    2486  General Public License.
    2487
    2488    "The Library" refers to a covered work governed by this License,
    2489  other than an Application or a Combined Work as defined below.
    2490
    2491    An "Application" is any work that makes use of an interface provided
    2492  by the Library, but which is not otherwise based on the Library.
    2493  Defining a subclass of a class defined by the Library is deemed a mode
    2494  of using an interface provided by the Library.
    2495
    2496    A "Combined Work" is a work produced by combining or linking an
    2497  Application with the Library.  The particular version of the Library
    2498  with which the Combined Work was made is also called the "Linked
    2499  Version".
    2500
    2501    The "Minimal Corresponding Source" for a Combined Work means the
    2502  Corresponding Source for the Combined Work, excluding any source code
    2503  for portions of the Combined Work that, considered in isolation, are
    2504  based on the Application, and not on the Linked Version.
    2505
    2506    The "Corresponding Application Code" for a Combined Work means the
    2507  object code and/or source code for the Application, including any data
    2508  and utility programs needed for reproducing the Combined Work from the
    2509  Application, but excluding the System Libraries of the Combined Work.
    2510
    2511    1. Exception to Section 3 of the GNU GPL.
    2512
    2513    You may convey a covered work under sections 3 and 4 of this License
    2514  without being bound by section 3 of the GNU GPL.
    2515
    2516    2. Conveying Modified Versions.
    2517
    2518    If you modify a copy of the Library, and, in your modifications, a
    2519  facility refers to a function or data to be supplied by an Application
    2520  that uses the facility (other than as an argument passed when the
    2521  facility is invoked), then you may convey a copy of the modified
    2522  version:
    2523
    2524     a) under this License, provided that you make a good faith effort to
    2525     ensure that, in the event an Application does not supply the
    2526     function or data, the facility still operates, and performs
    2527     whatever part of its purpose remains meaningful, or
    2528
    2529     b) under the GNU GPL, with none of the additional permissions of
    2530     this License applicable to that copy.
    2531
    2532    3. Object Code Incorporating Material from Library Header Files.
    2533
    2534    The object code form of an Application may incorporate material from
    2535  a header file that is part of the Library.  You may convey such object
    2536  code under terms of your choice, provided that, if the incorporated
    2537  material is not limited to numerical parameters, data structure
    2538  layouts and accessors, or small macros, inline functions and templates
    2539  (ten or fewer lines in length), you do both of the following:
    2540
    2541     a) Give prominent notice with each copy of the object code that the
    2542     Library is used in it and that the Library and its use are
    2543     covered by this License.
    2544
    2545     b) Accompany the object code with a copy of the GNU GPL and this license
    2546     document.
    2547
    2548    4. Combined Works.
    2549
    2550    You may convey a Combined Work under terms of your choice that,
    2551  taken together, effectively do not restrict modification of the
    2552  portions of the Library contained in the Combined Work and reverse
    2553  engineering for debugging such modifications, if you also do each of
    2554  the following:
    2555
    2556     a) Give prominent notice with each copy of the Combined Work that
    2557     the Library is used in it and that the Library and its use are
    2558     covered by this License.
    2559
    2560     b) Accompany the Combined Work with a copy of the GNU GPL and this license
    2561     document.
    2562
    2563     c) For a Combined Work that displays copyright notices during
    2564     execution, include the copyright notice for the Library among
    2565     these notices, as well as a reference directing the user to the
    2566     copies of the GNU GPL and this license document.
    2567
    2568     d) Do one of the following:
    2569
    2570         0) Convey the Minimal Corresponding Source under the terms of this
    2571         License, and the Corresponding Application Code in a form
    2572         suitable for, and under terms that permit, the user to
    2573         recombine or relink the Application with a modified version of
    2574         the Linked Version to produce a modified Combined Work, in the
    2575         manner specified by section 6 of the GNU GPL for conveying
    2576         Corresponding Source.
    2577
    2578         1) Use a suitable shared library mechanism for linking with the
    2579         Library.  A suitable mechanism is one that (a) uses at run time
    2580         a copy of the Library already present on the user's computer
    2581         system, and (b) will operate properly with a modified version
    2582         of the Library that is interface-compatible with the Linked
    2583         Version.
    2584
    2585     e) Provide Installation Information, but only if you would otherwise
    2586     be required to provide such information under section 6 of the
    2587     GNU GPL, and only to the extent that such information is
    2588     necessary to install and execute a modified version of the
    2589     Combined Work produced by recombining or relinking the
    2590     Application with a modified version of the Linked Version. (If
    2591     you use option 4d0, the Installation Information must accompany
    2592     the Minimal Corresponding Source and Corresponding Application
    2593     Code. If you use option 4d1, you must provide the Installation
    2594     Information in the manner specified by section 6 of the GNU GPL
    2595     for conveying Corresponding Source.)
    2596
    2597    5. Combined Libraries.
    2598
    2599    You may place library facilities that are a work based on the
    2600  Library side by side in a single library together with other library
    2601  facilities that are not Applications and are not covered by this
    2602  License, and convey such a combined library under terms of your
    2603  choice, if you do both of the following:
    2604
    2605     a) Accompany the combined library with a copy of the same work based
    2606     on the Library, uncombined with any other library facilities,
    2607     conveyed under the terms of this License.
    2608
    2609     b) Give prominent notice with the combined library that part of it
    2610     is a work based on the Library, and explaining where to find the
    2611     accompanying uncombined form of the same work.
    2612
    2613    6. Revised Versions of the GNU Lesser General Public License.
    2614
    2615    The Free Software Foundation may publish revised and/or new versions
    2616  of the GNU Lesser General Public License from time to time. Such new
    2617  versions will be similar in spirit to the present version, but may
    2618  differ in detail to address new problems or concerns.
    2619
    2620    Each version is given a distinguishing version number. If the
    2621  Library as you received it specifies that a certain numbered version
    2622  of the GNU Lesser General Public License "or any later version"
    2623  applies to it, you have the option of following the terms and
    2624  conditions either of that published version or of any later version
    2625  published by the Free Software Foundation. If the Library as you
    2626  received it does not specify a version number of the GNU Lesser
    2627  General Public License, you may choose any version of the GNU Lesser
    2628  General Public License ever published by the Free Software Foundation.
    2629
    2630    If the Library as you received it specifies that a proxy can decide
    2631  whether future versions of the GNU Lesser General Public License shall
    2632  apply, that proxy's public statement of acceptance of any version is
    2633  permanent authorization for you to choose that version for the
    2634  Library.

    2766
    2767  The licenses granted in Section 2.1 with respect to any Contribution

    2769  distributes such Contribution.
    2770
    2771  2.3. Limitations on Grant Scope
    2772
    2773  The licenses granted in this Section 2 are the only rights granted under
    2774  this License. No additional rights or licenses will be implied from the
    2775  distribution or licensing of Covered Software under this License.
    2776  Notwithstanding Section 2.1(b) above, no patent license is granted by a
    2777  Contributor:
    2778
    2779  (a) for any code that a Contributor has removed from Covered Software;
    2780      or
    2781
    2782  (b) for infringements caused by: (i) Your and any other third party's
    2783      modifications of Covered Software, or (ii) the combination of its

    2793
    2794  2.4. Subsequent Licenses

    2796  No Contributor makes additional grants as a result of Your choice to
    2797  distribute the Covered Software under a subsequent version of this
    2798  License (see Section 10.2) or under the terms of a Secondary License (if
    2799  permitted under the terms of Section 3.3).
    2800
    2801  2.5. Representation
    2802

    2818  3. Responsibilities
    2819  -------------------
    2820
    2821  3.1. Distribution of Source Form
    2822
    2823  All distribution of Covered Software in Source Code Form, including any
    2824  Modifications that You create or to which You contribute, must be under
    2825  the terms of this License. You must inform recipients that the Source
    2826  Code Form of the Covered Software is governed by the terms of this
    2827  License, and how they can obtain a copy of this License. You may not
    2828  attempt to alter or restrict the recipients' rights in the Source Code
    2829  Form.
    2830
    2831  3.2. Distribution of Executable Form
    2832
    2833  If You distribute Covered Software in Executable Form then:
    2834
    2835  (a) such Covered Software must also be made available in Source Code
    2836      Form, as described in Section 3.1, and You must inform recipients of
    2837      the Executable Form how they can obtain a copy of such Source Code
    2838      Form by reasonable means in a timely manner, at a charge no more
    2839      than the cost of distribution to the recipient; and
    2840
    2841  (b) You may distribute such Executable Form under the terms of this
    2842      License, or sublicense it under different terms, provided that the
    2843      license for the Executable Form does not attempt to limit or alter
    2844      the recipients' rights in the Source Code Form under this License.
    2845
    2846  3.3. Distribution of a Larger Work
    2847
    2848  You may create and distribute a Larger Work under terms of Your choice,
    2849  provided that You also comply with the requirements of this License for
    2850  the Covered Software. If the Larger Work is a combination of Covered
    2851  Software with a work governed by one or more Secondary Licenses, and the
    2852  Covered Software is not Incompatible With Secondary Licenses, this
    2853  License permits You to additionally distribute such Covered Software
    2854  under the terms of such Secondary License(s), so that the recipient of
    2855  the Larger Work may, at their option, further distribute the Covered
    2856  Software under the terms of either this License or such Secondary
    2857  License(s).
    2858
    2859  3.4. Notices
    2860
    2861  You may not remove or alter the substance of any license notices
    2862  (including copyright notices, patent notices, disclaimers of warranty,
    2863  or limitations of liability) contained within the Source Code Form of
    2864  the Covered Software, except that You may alter any license notices to
    2865  the extent required to remedy known factual inaccuracies.
    2866
    2867  3.5. Application of Additional Terms
    2868
    2869  You may choose to offer, and to charge a fee for, warranty, support,
    2870  indemnity or liability obligations to one or more recipients of Covered
    2871  Software. However, You may do so only on Your own behalf, and not on
    2872  behalf of any Contributor. You must make it absolutely clear that any
    2873  such warranty, support, indemnity, or liability obligation is offered by
    2874  You alone, and You hereby agree to indemnify every Contributor for any
    2875  liability incurred by such Contributor as a result of warranty, support,
    2876  indemnity or liability terms You offer. You may include additional
    2877  disclaimers of warranty and limitations of liability specific to any
    2878  jurisdiction.
    2879
    2880  4. Inability to Comply Due to Statute or Regulation
    2881  ---------------------------------------------------
    2882
    2883  If it is impossible for You to comply with any of the terms of this
    2884  License with respect to some or all of the Covered Software due to
    2885  statute, judicial order, or regulation then You must: (a) comply with
    2886  the terms of this License to the maximum extent possible; and (b)
    2887  describe the limitations and the code they affect. Such description must
    2888  be placed in a text file included with all distributions of the Covered
    2889  Software under this License. Except to the extent prohibited by statute
    2890  or regulation, such description must be sufficiently detailed for a
    2891  recipient of ordinary skill to be able to understand it.
    2892
    2893  5. Termination
    2894  --------------
    2895
    2896  5.1. The rights granted under this License will terminate automatically
    2897  if You fail to comply with any of its terms. However, if You become
    2898  compliant, then the rights granted under this License from a particular
    2899  Contributor are reinstated (a) provisionally, unless and until such
    2900  Contributor explicitly and finally terminates Your grants, and (b) on an
    2901  ongoing basis, if such Contributor fails to notify You of the
    2902  non-compliance by some reasonable means prior to 60 days after You have
    2903  come back into compliance. Moreover, Your grants from a particular
    2904  Contributor are reinstated on an ongoing basis if such Contributor
    2905  notifies You of the non-compliance by some reasonable means, this is the
    2906  first time You have received notice of non-compliance with this License
    2907  from such Contributor, and You become compliant prior to 30 days after
    2908  Your receipt of the notice.
    2909
    2910  5.2. If You initiate litigation against any entity by asserting a patent
    2911  infringement claim (excluding declaratory judgment actions,
    2912  counter-claims, and cross-claims) alleging that a Contributor Version
    2913  directly or indirectly infringes any patent, then the rights granted to
    2914  You by any and all Contributors for the Covered Software under Section
    2915  2.1 of this License shall terminate.
    2916
    2917  5.3. In the event of termination under Sections 5.1 or 5.2 above, all
    2918  end user license agreements (excluding distributors and resellers) which
    2919  have been validly granted by You or Your distributors under this License
    2920  prior to termination shall survive termination.
