"""Convert REPs to (X)HTML - courtesy of /F
Usage: %(PROGRAM)s [options] [<reps> ...]
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 rep arguments are given, this
will browse REP 0.
-i, --install
After generating the HTML, install it and the plaintext source file
(.rst) 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 ``reps`` are either rep numbers or .rst files.
