So that there is less stuff to update, it would be nice if pytz could use the system time zone database in /usr/share/zoneinfo. This would reduce the number of packages that need to be updated when new time zone data becomes available.

As a start, I've put together a branch that parses the binary time zone data files at runtime instead of generating Python source files. This provides equivalent functionality, and by replacing the pytz/zoneinfo directory with a symlink to /usr/share/zoneinfo, it will use the system database.
