"""Dump the contents of any Mailman `database' file.
Usage: %(PROGRAM)s [options] filename
Options:
--marshal/-m
Assume the file contains a Python marshal, overridding any automatic
guessing.
--pickle/-p
Assume the file contains a Python pickle, overridding any automatic
guessing.
--noprint/-n
Don't attempt to pretty print the object. This is useful if there's
some problem with the object and you just want to get an unpickled
representation. Useful with `python -i bin/dumpdb <file>'. In that
case, the root of the tree will be left in a global called "msg".
--help/-h
Print this help message and exit
If the filename ends with `.db', then it is assumed that the file contains a
Python marshal. If the file ends with `.pck' then it is assumed to contain a
Python pickle. In either case, if you want to override the default assumption
-- or if the file ends in neither suffix -- use the -p or -m flags.
