Re: Re: [Python-Dev] anyone tried to use optparse with something else than sys.argv?

First bit of bad news: the optparse.py in Python's library is
automatically generated from the Optik source, so patching optparse.py
is a waste of time.  You'll need to get the Optik CVS tree from
optik.sourceforge.net and hack on that.

Sounds reasonable on the surface, but I'll need to look at your patch in
detail before making up my mind.

That I'm not so sure about.  Hmmm.

I'm going to have to sit down with the list of problems you posted to
python-dev and come up with my own solutions.  *Then* I'll understand
your solutions.  We'll probably agree on some points and not on others
-- that's life.
