 | 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." | 
 |  | 
 | :mod:`ihooks` | 
 |    --- Import hook support (for :mod:`rexec`; may become obsolete).  Removed in | 
 |    Python 3.x. | 
 |  | 
 |  | 
 | Platform specific modules | 
 | ========================= | 
 |  | 
 | These modules are used to implement the :mod:`os.path` module, and are not | 
 | documented beyond this mention.  There's little need to document these. | 
 |  | 
 | :mod:`ntpath` | 
 |    --- Implementation of :mod:`os.path` on Win32, Win64, WinCE, and OS/2 platforms. | 
 |  | 
 | :mod:`posixpath` | 
 |    --- Implementation of :mod:`os.path` on POSIX. | 
 |  | 
 | :mod:`bsddb185` | 
 |    --- Backwards compatibility module for systems which still use the Berkeley DB | 
 |    1.85 module.  It is normally only available on certain BSD Unix-based systems. | 
 |    It should never be used directly. | 
 |  | 
 |  | 
 | Multimedia | 
 | ========== | 
 |  | 
 | :mod:`audiodev` | 
 |    --- Platform-independent API for playing audio data.  Removed in Python 3.x. | 
 |  | 
 | :mod:`linuxaudiodev` | 
 |    --- Play audio data on the Linux audio device.  Replaced in Python 2.3 by the | 
 |    :mod:`ossaudiodev` module.  Removed in Python 3.x. | 
 |  | 
 | :mod:`sunaudio` | 
 |    --- Interpret Sun audio headers (may become obsolete or a tool/demo). | 
 |    Removed in Python 3.x. | 
 |  | 
 | :mod:`toaiff` | 
 |    --- Convert "arbitrary" sound files to AIFF files; should probably become a tool | 
 |    or demo.  Requires the external program :program:`sox`.  Removed in Python 3.x. | 
 |  |

 | .. _obsolete-modules: | 
 |  | 
 | Obsolete | 
 | ======== | 
 |  | 
 | These modules are not normally available for import; additional work must be | 
 | done to make them available. | 
 |  | 
 | These extension modules written in C are not built by default. Under Unix, these | 
 | must be enabled by uncommenting the appropriate lines in :file:`Modules/Setup` | 
 | in the build tree and either rebuilding Python if the modules are statically | 
 | linked, or building and installing the shared object if using dynamically-loaded | 
 | extensions. | 
 |  | 
 | .. (lib-old is empty as of Python 2.5) | 
 |  | 
 |    Those which are written in Python will be installed into the directory | 
 |    \file{lib-old/} installed as part of the standard library.  To use | 
 |    these, the directory must be added to \code{sys.path}, possibly using | 
 |    \envvar{PYTHONPATH}. | 
 |  | 
 | :mod:`timing` | 
 |    --- Measure time intervals to high resolution (use :func:`time.clock` | 
 |    instead).  Removed in Python 3.x. | 
 |  | 
 |  | 
 | SGI-specific Extension modules | 
 | ============================== | 
 |  | 
 | The following are SGI specific, and may be out of touch with the current version | 
 | of reality. | 
 |  | 
 | :mod:`cl` | 
 |    --- Interface to the SGI compression library. | 
 |  | 
 | :mod:`sv` | 
 |    --- Interface to the "simple video" board on SGI Indigo (obsolete hardware). | 
 |    Removed in Python 3.x. |
