"""
This is a tool for exploring module documentation trees generated by
``docutils.readers.python.moduleparser.parse_module()`` from test data in
docutils/test/test_readers/test_python/test_parser or stdin.

Usage::

    showdoc <key> <index>

    showdoc < <module.py>

Where ``<key>`` is the key to the ``totest`` dictionary, and ``<index>`` is
the index of the list ``totest[key]``.  If no arguments are given, stdin is
used for input.
