=head1 create-plan.pl

Creates a new account plan for use with virtual servers.

This command allows you to create a new account plan, which defines limits
that can be applied to new or existing virtual servers. The only mandatory
parameter is C<--name>, which must be followed by a unique name for the plan
to create.

Quotas for virtual servers on the plan can be set with the C<--quota> or
C<--admin-quota> flags, followed by a quota in blocks (typically 1k in size).
By default, plan quotas are unlimited.

Restrictions on the number of virtual servers, mailboxes, aliases and databases
can be set with the C<--max-doms>, C<--max-mailbox>, C<--max-alias> and
C<--max-dbs> parameters, followed by a number. By default, all of these are
unlimited.

Allowed features for new virtual servers can be set with the C<--features> flag,
followed by a space-separated feature code list like I<web dns mail>. Similarly,
allowed editing capabilities can be set with C<--capabilities> followed by
a list of codes like I<domain users aliases>. In both cases, the lists must
be a single quoted parameter.

Scripts that virtual servers on the plan can install can be restricted by
the C<--scripts> flag, followed by a quoted list of script codes. To find
available codes, use the C<list-available-scripts> API command.

To create a plan that is owned by a reseller, use the C<--owner> flag followed
by an existing reseller name. To limit use of the plan to only some resellers,
use C<--resellers> followed by a list of reseller names. Or use
C<--no-resellers> to prevent any resellers from seeing it.
