No.  :-/  Sorry.

Calm, calm.

I wasn't talking about unittest.main.  My quick look at the source at
the time I wrote that script I pointed you to made it clear that
unittest.main was implemented in terms of stuff that was designed to
be easily re-used, so I assumed you must not have looked at the source
(and the docstrings therein).  Hmm, did I mention the source?  I meant
to...

:-) It works, with minimal effort.  A good pragmatic solution if name
clashes are not likely and you have a relatively small amount of code.

(Not sure which discussions you mean there.)

Hmm.  It's a few years since I read them, I admit, but looking at the
docstrings now (I should have mentioned the docstrings, of course),
they don't look bad, for a module of only 750-odd lines (including
the docstrings!).
