"""Convert PEPs to (X)HTML - courtesy of /F
Usage: %(PROGRAM)s [options] [peps]
Options:
-u/--user
python.org username
-b/--browse
After generating the HTML, direct your web browser to view it
(using the Python webbrowser module). If both -i and -b are
given, this will browse the on-line HTML; otherwise it will
browse the local HTML. If no pep arguments are given, this
will browse PEP 0.
-i/--install
After generating the HTML, install it and the plaintext source file
(.txt) on python.org. In that case the user's name is used in the scp
and ssh commands, unless "-u username" is given (in which case, it is
used instead). Without -i, -u is ignored.
-q/--quiet
Turn off verbose messages.
-h/--help
Print this help message and exit.
The optional argument `peps' is a list of either pep numbers or .txt files.
