"""Remove the components of a mailing list with impunity - beware!

This removes (almost) all traces of a mailing list.  By default, the lists
archives are not removed, which is very handy for retiring old lists.

Usage:
    rmlist [-a] [-h] listname

Where:
    --archives
    -a
        Remove the list's archives too, or if the list has already been
        deleted, remove any residual archives.

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