"""Clone a member address.

Cloning a member address means that a new member will be added who has all the
same options and passwords as the original member address.  Note that this
operation is fairly trusting of the user who runs it -- it does no
verification to the new address, it does not send out a welcome message, etc.

The existing member's subscription is not modified in any way.  If you want to
remove it, you need to run the `remove_members' script explicitly.

Usage:
    clone_member [-h] listname fromaddr toaddr

Where:

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

    listname is the name of the mailing list to find the address on.

    fromaddr is the address of the user to clone from

    toaddr is the address of the user to clone to
