# This python script creates Finder aliases for all the
# dynamically-loaded modules that "live in" in a single
# shared library.
# It needs a fully functional non-dynamic python to work
# (since it creates aliases to stuff it needs itself),
# you should probably drag it onto your non-dynamic python.
# 
# If you compare it to MkPluginAliases.as it also serves
# as a comparison between python and AppleScript:-)
