Undocumented Modules ******************** Here's a quick listing of modules that are currently undocumented, but that should be documented. Feel free to contribute documentation for them! (Send via email to docs@python.org.) The idea and original contents for this chapter were taken from a posting by Fredrik Lundh; the specific contents of this chapter have been substantially revised. Miscellaneous useful utilities ============================== Some of these are very old and/or not very robust; marked with "hmm." ``ihooks`` --- Import hook support (for ``rexec``; may become obsolete). Removed in Python 3.x. Platform specific modules ========================= These modules are used to implement the ``os.path`` module, and are not documented beyond this mention. There's little need to document these. ``ntpath`` --- Implementation of ``os.path`` on Win32, Win64, WinCE, and OS/2 platforms. ``posixpath`` --- Implementation of ``os.path`` on POSIX.
