=head1 create-template.pl

Creates a template for use by new domains.

This command can be used to create a new virtual server template, whose name
is set by the C<--name> parameter. You can either have the template created
completely empty (so that all settings inherit from the default template)
with the C<--empty> flag, or you can clone an existing template with the
C<--clone> flag followed by a template name.
