I'm guessing this is re.sub (or, more likely, a method sub of an
internal object that is called by re.sub).

If all your script does is to make a bunch of regexp substitutions,
then spending 99% of the time in this function might be reasonable.
Optimize your regexps to improve performance.  (We can help you if you
care to share any.)

If my guess is wrong, you'll have to be more specific about what your
sctipt does, and maybe share the profile printout or something.
