"""
Avolites Pearl Expert Show File Cleanup Program
for The Chapel in Akron
by Mike Crute (mcrute@gmail.com)
on February 20, 2008

This is a simple GUI program that allows for the cleanup of Avolites Pearl
Expert show files in the new (directory-based) format. It requires a recent
version of Python (originally designed for 2.6) and a copy of wxPython.

The file is split into two parts, first is the Show File API that provides
very basic searching and interperation of the show files on disk. The
second part is all of the GUI code that renders the interface. The API code
has no dependency on the GUI code.
