Whey I do a help (python-module), I get the help text as follows:

Help on module tempfile:

NAME
    tempfile - Temporary files.

FILE
    /usr/lib/python2.5/tempfile.py

MODULE DOCS
    http://www.python.org/doc/2.5.4/lib/module-tempfile.html

DESCRIPTION
    This module provides generic, low- and high-level interfaces for
    creating temporary files and directories.  The interfaces listed
    as "safe" just below can be used without fear of race conditions.
    Those listed as "unsafe" cannot, and are provided for backward
    compatibility only.

The link to the webpage lists the supported platforms for the module.
It would be good to have an entry stating the list of platforms supported
by the module, in the module doc itself.
