I've used dumpdb before.  Definitely a useful tool.  But how _exactly_ do I
feed in edited dumped files ("marshaled dictionary"?) back into mailman
using dumpdb?  Can you send me the actual sequence of shell commands?

Maybe there's some python magic I'm not familiar with; but dumpdb doesn't
appear to take stdin, and seems always to want to have an argv[1] specifying
a .db file of that .db format.

It'll be great if I could use dumpdb to re-configure an entire list.

Thanks,
Erez.
