=head1 delete-shared-address.pl
Removes an IP address that can be used by virtual servers
This command takes a single IP address out of the list available for use by
multiple virtual servers, specified with the C<--ip> flag. If the
C<--deactivate> flag is also given, the virtual interface associated with the
IP will also be shut down.
