+'''Helper script for bundling up a game in a ZIP file.

+This script will bundle all game files into a ZIP file which is named as
+per the argument given on the command-line. The ZIP file will unpack into a
+directory of the same name.
+
+The script ignores:
+
+- CVS or SVN subdirectories
+- any dotfiles (files starting with ".")
+- .pyc and .pyo files
