optparse uses sys.argv[0] for the program name even if
you supply the   
prog argument to OptionParser.__init__

ie, if you have p = OptionParser(prog='NEW_NAME'),
p.print_usage, p.print_help, p.error, etc. don't use
NEW_NAME as %prog.

This is with Python 2.3.2

I've submitted a patch.
See : http://www.python.org/sf/851902

Please apply the patch and check if "prog" argument 
works.

Thank you.

Unfortunately, the patch breaks some of the existing tests
for optparse.  I've committed a fix that doesn't require
changing the existing tests and that adds new tests so this
doesn't break in the future.

Fixed for Python 2.3.4 and 2.4:

Lib/optparse.py  1.8, 1.5.8.2
Lib/test/test_optparse.py  1.3, 1.2.8.2
