+****************
+Data Persistence
+****************
+
+The modules described in this chapter support storing Python data in a
+persistent form on disk.  The :mod:`pickle` and :mod:`marshal` modules can turn
+many Python data types into a stream of bytes and then recreate the objects from
+the bytes.  The various DBM-related modules support a family of hash-based file
+formats that store a mapping of strings to other strings.  The :mod:`bsddb`
+module also provides such disk-based string-to-string mappings based on hashing,
+and also supports B-Tree and record-based formats.
+
+The list of modules described in this chapter is:
