    So, if you're not down to slap an "r" before your string literals,

Never heard of that before, but it did the trick.

   Long story short, those double backslashes in your regex?
   They'll be quadrupling up in your Python string literal!

for line in lines:
     product = re.search( "\\sout\{", line )

This also worked.
For now, I'll use the "r" in a cargo-cult fashion, until I decide which
syntax I prefer. (Is there any reason that one or the other is preferable?)
Thanks for your help,
Mike
