=head1 modify-plan.pl

Modifies an existing account plan for use with virtual servers.

This command allows you to modify the limits for an existing account plan,
and optionally apply it to all virtual servers currently on that plan
(with the C<--apply> flag). Its parameters are exactly the same as
C<create-plan>, so for full documentation you should refer to that command.

To change the name of a plan, use the C<--new-name> flag followed by the
new name of your choice.
