+tdbpack provides a means of pickling values into binary formats
+compatible with that used by the samba tdbpack()/tdbunpack()
+functions.
+
+Numbers are always stored in little-endian format; strings are stored
+in either DOS or Unix codepage as appropriate.
+
+The format for any particular element is encoded as a short ASCII
+string, with one character per field."""
