"""
convert PEP's to (X)HTML - courtesy of /F
Usage: %(PROGRAM)s [options] [peps]
Notes:
The optional argument peps can be either pep numbers or .txt files.
Options:
-u/--user
SF username
-i/--install
After generating the HTML, install it SourceForge. In that case the
user's name is used in the scp and ssh commands, unless sf_username is
given (in which case, it is used instead). Without -i, sf_username is
ignored.
-h/--help
Print this help message and exit.
