# This script creates the 'temoa.py' zip archive/executable.  I do not know if
# it is portable, but I know that it correctly creates the executable with the
# Ubuntu Linux distribution's version of Zip, Info-ZIP.

# To create the archive, execute with no arguments (in this directory), or
# with '--save'.  The save argument merely saves the temporary zip file from
# which 'temoa.py' is created.
