Thanks for the help Tim.  I just copied and pasted your code into a
file in my $PYTHONPATH (IndentedHelpFormatterWithNL.py), but I'm
getting the following error:

    class IndentedHelpFormatterWithNL(IndentedHelpFormatter):
NameError: name 'IndentedHelpFormatter' is not defined


I tried adding: from optparse imoport IndentedHelpFormatter into the
aforementioned file, but no luck again.  What am I missing???

Thanks.
