#!/bin/bash
#############################################################
# list_mailman_list_members
#                              
# Bash script to log in to a server running Mailman
# software and generate a list of members of each list.
#
# Configurable Parameters:
#
#   SERVER: Hostname, FQDN or alias in your SSH config for the server
#   
#   USER: Which user to log in as on that server. You must be able to SSH
#         in with this user, preferably without a password (key authentication)
#
#   USESUDO: Uncomment if you that user needs sudo for the mailman commands
#
#   MM_PATH: Where to find Mailman commands on the remote server. Debian/Ubuntu
#         package installer puts them in /usr/sbin/ but installing from source
#         and not changing default $prefix puts them in /usr/local/mailman/bin/.
#         you can blank or comment out the line if you are sure it is in the default
#         $PATH.
#
# Todo:
#    - Error checking
#    - Nicer report options?
