# This code is not fully functinal. It is only the start 
# of an idea I have, but I don't have time to finish it 
# right now.
#
# Ideally, this script will be able to convert LaTeX
# sections to Creole headings, convert basic tables and
# bulleted/itemized lists. Nothing too fancy. Just a way
# to use existing LaTeX documentation in WIKIs instead of
# trying to convert everything yourself...
