"""
This is a tweaked version of the copy found in http://hg.python.org/peps.
Some of the HTML output is changed but the logic remains mostly the same. It
proved easier to update this file than replicate the logic without error.

"""
"""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.
-l, --local
Same as -i/--install, except install on the local machine. Use this
when logged in to the python.org machine (dinsdale).
-q, --quiet
Turn off verbose messages.
-h, --help
Print this help message and exit.
The optional arguments ``peps`` are either pep numbers or .txt files.
