Sorry, I forgot to tell you that you also need a file named __init__.py 
in the appcomponents directory in order for the appcomponents directory 
to act as a package; that's how Python works. Just make a new blank 
file or copy the one that is already in the components directory.

There are logging messages in the PythonCard framework to show what 
components are loaded and from where, so if you run your application 
with the -l command-line option you'll get a pythoncard.log file or 
output to stdout with a line that looks something like:

DEBUG: : Mon Sep 13 07:48:07 2004: imported appcomponent multicolumnlist


PythonCard customization note:
Whether the output goes to stdout (the default) or not is controlled by 
a line in your pythoncard_config.txt file in 
~/pythoncard_config/pythoncard_config.txt on *nix systems, including 
Mac OS X or your My Documents/pythoncard_config/pythoncard_config.txt 
or similar user directory on Windows systems, which is roughly 
equivalent to the home directory on *nix. The relevant lines are:

    'logfile':'pythoncard.log',
    'logToStdout':True,
