=head1 DESCRIPTION

This program will read the given input file and output a GIF image of a
pink pony.

The input file may be a hyphen to indicate input from STDIN. The output
file may be a hyphen to indicate output to STDOUT. If the input is from
a file and the output file is omitted, the script will invent a filename
for output by replacing the input script's ".pl" file extension with
".gif".
