# This script can be used to identify undocumented modules in the Python
# standard library. Use it like this:
#
# .../Doc/tools/listmodules --ignore-from .../Doc/paper-<paper>/modlib.idx
"""%(program)s - list modules in the Python standard library
-a, --annotate Annotate the module names with the subdirectory they
live in
-c, --categorize Group the modules by subdirectory
-i <file>,
--ignore-from <file> Ignore the modules listed in <file>. <file> may
contain a list of module names or a module index file
as produced when formatting the Python documentation
(.idx or .html flavor).
If neither -a nor -c are given, the modules are listed in alphabetical
order.
Note that -a and -c are mutually exclusive.
Limitation: Modules loadable as shared objects may not be listed,
though this script attempts to locate such modules.
