"""Send password reminders for all lists to all users.
This program scans all mailing lists and collects users and their passwords,
grouped by the list's host_name if mm_cfg.VIRTUAL_HOST_OVERVIEW is true. Then
one email message is sent to each unique user (per-virtual host) containing
the list passwords and options url for the user. The password reminder comes
from the mm_cfg.MAILMAN_SITE_LIST, which must exist.
Usage: %(PROGRAM)s [options]
Options:
-l listname
--listname=listname
Send password reminders for the named list only. If omitted,
reminders are sent for all lists. Multiple -l/--listname options are
allowed.
-h/--help
Print this message and exit.
