If you use »bzr builddeb« you can leave this script alone as it will
be run at the right places auto-magically. Otherwise you should use
»pre-export« to update po and pot files as well as version numbering.
»post-build« can be used to run some more or less useful checks later on.

»library« isn't run automatically but can be useful for maintaining the
(more or less experimental) symbols files we provide"
