###
###  This is a utility script we used to do a one-time synchronization
###  of our subscribers' website login passwords with their Mailman
###  mailing list passwords for the emails corresponding with their
###  website login accounts.
###
###  It will not be useful to you in its present form because it
###  refers to some custom Python objects relating to our website
###  login and membership database.  However it's being provided for
###  an example of code you might need to write for a list migration.
###
###  For each list:
###    For each subscriber:
###      If email belongs to a member:
###        If member has a website login:
###          Set passwd for email on list to website login passwd
###        Else (member doesn't have a website login):
###          Set passwd for email on list to some default passwd
###      Else (email doesn't belong to a member):
###        Set passwd for email on list to some default passwd
