"""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.
