=head1 list-templates.pl

List available templates for new domains

The command simply outputs a list of available templates for use when
creating new virtual servers. For each the ID number and description
are displayed.

To just display the template names, you can give the C<--name-only> parameter.
This is useful when iterating through them in other scripts.

By default, deleted templates are not included in the list unless you
add the C<--deleted> flag.
