"""Add members to a list from the command line.

Usage:
    subscribe_list [options] listname [listname ...]

Options:

    --regular-member=addr1
    -r addr1
        Add addr1 as a regular (non-digest) member.

    --digest-member=addr1
    -d addr1
        Add add1 as a digest member.

    --welcome-msg=<y|n>
    -w <y|n>
        Set whether or not to send the list members a welcome message,
        overriding whatever the list's `send_welcome_msg' setting is.

    --admin-notify=<y|n>
    -a <y|n>
        Set whether or not to send the list administrators a notification on
        the success/failure of these subscriptions, overriding whatever the
        list's `admin_notify_mchanges' setting is.

    --help
    -h
        Print this help message and exit.

    listname
        The name of the Mailman list you are adding members to.  It must
        already exist.

You must supply at least one of -n and -d options.  At most one of the
files can be `-'.
