Update pytz timezone definitions

I am looking at using pytz in a scheduling application which will be
used internationally. I would like to be able to update the definition
files that pytz uses monthly or bi-monthly.
As far as I can tell, pytz seems to be updated (fairly) regularly to
the newest tzdata, but I don't want to have to update my pytz, just
it's definitions.
http://www.twinsun.com/tz/t...
says that pytz "compiles tz
source into Python." Does this mean that there is already a method for
updating the definitions?
Any help would be greatly appreciated, even if it is to point out
something obvious which I over looked.

pytz's build process is rather complicated (e.g., a list of all time
zones is appended to pytz/__init__.py). I really don't think it would be
worth the effort.
python-dateutil [1] [2] provides time zone support similar to pytz's,
among other features. It keeps the time zone files in a tarball and I'm
pretty sure it would be easy to update.
I still don't get why you'd want to go to the effort though. Upgrading
the whole package is easy. It's not like pytz gets a new API every version.
