-# tdbutil
-#
-# Purpose:
-# Contains functions that are used to pack and unpack data
-# from Samba's tdb databases. Samba sometimes represents complex
-# data structures as a single value in a database. These functions
-# allow other python scripts to package data types into a single python
-# string and unpackage them.
-#
-#
-# XXXXX: This code is no longer used; it's just here for testing
-# compatibility with the new (much faster) C implementation.
