=head1 delete-user.pl

Delete a mail, FTP or database user

This command deletes one mail, FTP or database user from a virtual server,
along with him home directory. It takes only two parameters, both mandatory :
C<--domain> followed by the domain name, and C<--user> followed by the full or short username. Be careful with this program, as it does not prompt for confirmation before deleting.
