+# 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.
