"""Create a new, unpopulated mailing list.

Usage: %(PROGRAM)s [options] [listname [listadmin-addr [admin-password]]]

Options:

    -l language
    --language language
        Make the list's preferred language `language', which must be a two
        letter language code.

    -q/--quiet
        Normally the administrator is notified by email (after a prompt) that
        their list has been created.  This option suppresses the prompt and
        notification.

    -h/--help
        Print this help text and exit.

You can specify as many of the arguments as you want on the command line:
you will be prompted for the missing ones.

Every Mailman list has two parameters which define the default host name for
outgoing email, and the default URL for all web interfaces.  When you
configured Mailman, certain defaults were calculated, but if you are running
multiple virtual Mailman sites, then the defaults may not be appropriate for
the list you are creating.

You can specify the domain to create your new list in by spelling the listname
like so:

    mylist@www.mydom.ain

where `www.mydom.ain' should be the base hostname for the URL to this virtual
hosts's lists.  E.g. with is setting people will view the general list
overviews at http://www.mydom.ain/mailman/listinfo.  Also, www.mydom.ain
should be a key in the VIRTUAL_HOSTS mapping in mm_cfg.py/Defaults.py.  It
will be looked up to give the email hostname.  If this can't be found, then
www.mydom.ain will be used for both the web interface and the email
interface.

If you spell the list name as just `mylist', then the email hostname will be
taken from DEFAULT_EMAIL_HOST and the url will be taken from DEFAULT_URL (as
defined in your Defaults.py file or overridden by settings in mm_cfg.py).

Note that listnames are forced to lowercase.
