=head1 clone-domain.pl

Duplicates an existing virtual server with a new name.

This command will duplicate an existing virtual server with a new
domain name. Any web content, DNS records, mailboxes, mail aliases, databases
and other settings associated with the original domain will be duplicated,
where possible.

The virtual server to clone is selected with the C<--domain> flag, and the
new name is set with the C<--newdomain> parameter. When cloning a top-level
server the C<--newuser> and C<--newpass> flags can be used to set the login
and password of the new user that will be created as part of the cloning
process.
