## Examples

You can add owners or moderators, optionally with a display name, to a mailing list from the command line.

    >>> from mailman.app.lifecycle import create_list
    >>> bee = create_list('bee@example.com')
    >>> command('mailman admins --add "Anne <aperson@example.com>" '
    ... 'bee.example.com')
    >>> from mailman.testing.documentation import dump_list
    >>> from operator import attrgetter
    >>> dump_list(bee.owners.addresses, key=attrgetter('email'))
    Anne <aperson@example.com>

    >>> command('mailman admins --add bperson@example.com '
    ...         '--role moderator bee.example.com')
    >>> dump_list(bee.moderators.addresses, key=attrgetter('email'))
    bperson@example.com

You can delete owners or moderators from a mailing list from the command line.

    >>> command('mailman admins --delete aperson@example.com bee.example.com')
    >>> dump_list(bee.owners.addresses, key=attrgetter('email'))
    *Empty*

You can add and delete in one command.

    >>> command('mailman admins --delete bperson@example.com '
    ...         '--add cperson@example.com --role moderator bee.example.com')
    >>> dump_list(bee.moderators.addresses, key=attrgetter('email'))
    cperson@example.com

Adding addesses which already have that role just results in a warning being printed.

    >>> command('mailman admins --add cperson@example.com '
    ...         '--role moderator bee.example.com')
    cperson@example.com is already a moderator of bee@example.com

Likewise, removing an address which doesn’t have that role just results in a warning being printed.

    >>> command('mailman admins --delete aperson@example.com bee.example.com')
    aperson@example.com is not a owner of bee@example.com
