"""Latex Splitter quickee python app.

This application assists in spliting large Latex files into lots of
smaller ones.

To use this application, paste a latex file into the window. Highlight
the section you wish to save as an independent fragment. Then hit the
button, give the fragment a file name and a topic, and save
it. Continue until you've retreived everything out of the file you
want.

Starting it with a command-line parameter will try to load that file
into the text box.

This program may require Python as high as 2.2, though 2.1 should
do."""
