Sure! :)

Ok to update other scripts, too. Just remember to follow a couple 
guidelines, please:

- use unix line endings (there's crlf.py, a script that comes with 
Python itself, for those using text editors without this option);
- scripts must include license information (gpl compatible) and good doc 
strings;
- usually scripts have version (+date) info; if the author forgot to 
update that, it's better to do so or ask them to.

Also, if more than one coder is updating scripts, they'd better talk to 
each other to avoid duplicate work or mistakes, of course.
