Script to help identify undocumented modules. Use -h or --help for

usage information.

Doc/tools/listmodules

+#! /usr/bin/env python
+#  -*- Python -*-
+#
+#  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 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 are not listed.
