Run this script to check a specific language file, or all of them.
Command line settings are in form --parameter[=value].
Parameters:
        --help: Show this help.
        --lang: Language code (default: the installation default language).
        --all: Check all customized languages.
        --level: Show the following display level (default: 2):
                * 0: Skip the checks (useful for checking syntax).
                * 1: Show only the stub headers and number of wrong messages, without list of messages.
                * 2: Show only the headers and the message keys, without the message values.
                * 3: Show both the headers and the complete messages, with both keys and values.
        --links: Link the message values (default off).
        --prefix: prefix to add to links.
        --wikilang: For the links, what is the content language of the wiki to display the output in (default en).
        --noexif: Don't check for EXIF messages (a bit hard and boring to translate), if you know
                that they are currently not translated and want to focus on other problems (default off).
        --whitelist: Do only the following checks (form: code,code).
        --blacklist: Don't do the following checks (form: code,code).
        --easy: Do only the easy checks, which can be treated by non-speakers of the language.

Check codes (ideally, all of them should result 0; all the checks are executed by default (except language-specific check blacklists in checkLanguage.inc):
        * untranslated: Messages which are required to translate, but are not translated.
        * duplicate: Messages which translation equal to fallback
        * obsolete: Messages which are untranslatable or do not exist, but are translated.
        * variables: Messages without variables which should be used, or with variables which shouldn't be used.
        * empty: Empty messages and messages that contain only -.
        * whitespace: Messages which have trailing whitespace.
        * xhtml: Messages which are not well-formed XHTML (checks only few common errors).
        * chars: Messages with hidden characters.
        * links: Messages which contains broken links to pages (does not find all).
        * unbalanced: Messages which contains unequal numbers of opening {[ and closing ]}.
        * namespace: Namespace names that were not translated.
        * projecttalk: Namespace names and aliases where the project talk does not contain $1.
        * magic: Magic words that were not translated.
        * magic-old: Magic words which do not exist.
        * magic-over: Magic words that override the original English word.
        * magic-case: Magic words whose translation changes the case-sensitivity of the original English word.
        * special: Special page names that were not translated.
        * special-old: Special page names which do not exist.

Run this script to check the status of a specific language in extensions, or all of them.
Command line settings are in form --parameter[=value], except for the first one.
Parameters:
        * First parameter (mandatory): Extension name, multiple extension names (separated by commas), "all" for all the extensions, "wikimedia" for extensions used by Wikimedia or "flaggedrevs" for all FLaggedRevs extension messages.
        * lang: Language code (default: the installation default language).
        * help: Show this help.
        * level: Show the following display level (default: 2).
        * links: Link the message values (default off).
        * wikilang: For the links, what is the content language of the wiki to display the output in (default en).
        * whitelist: Do only the following checks (form: code,code).
        * blacklist: Do not perform the following checks (form: code,code).
        * easy: Do only the easy checks, which can be treated by non-speakers of the language.
Check codes (ideally, all of them should result 0; all the checks are executed by default (except language-specific check blacklists in checkLanguage.inc):
        * untranslated: Messages which are required to translate, but are not translated.
        * duplicate: Messages which translation equal to fallback
        * obsolete: Messages which are untranslatable, but translated.
        * variables: Messages without variables which should be used, or with variables which should not be used.
        * empty: Empty messages.
        * whitespace: Messages which have trailing whitespace.
        * xhtml: Messages which are not well-formed XHTML (checks only few common errors).
        * chars: Messages with hidden characters.
        * links: Messages which contains broken links to pages (does not find all).
        * unbalanced: Messages which contains unequal numbers of opening {[ and closing ]}.
Display levels (default: 2):
        * 0: Skip the checks (useful for checking syntax).
        * 1: Show only the stub headers and number of wrong messages, without list of messages.
        * 2: Show only the headers and the message keys, without the message values.
        * 3: Show both the headers and the complete messages, with both keys and values.
