"""A utility for browsing COM objects.
Usage:
Command Prompt
Use the command *"python.exe catbrowse.py"*. This will display
display a fairly small, modal dialog.
Pythonwin
Use the "Run Script" menu item, and this will create the browser in an
MDI window. This window can be fully resized.
Details
This module allows browsing of registered Type Libraries, COM categories,
and running COM objects. The display is similar to the Pythonwin object
browser, and displays the objects in a hierarchical window.
Note that this module requires the win32ui (ie, Pythonwin) diestribution to
work.
