=head1 get-template.pl

Outputs all settings in a template.

This command can be used to output all settings in a Virtualmin template,
specified either by name with the C<--name> parameter, or by ID with the
C<--id> flag. By default only values actually set in the template are output,
but you can add the C<--inherited> flag to include settings from the default
template too.

By default all settings are output, formatted like :

  aliascopy: 0
  aliasdomslimit: none
  aliaslimit: none
  etc..

Any newlines in multi-line values are converted to \n for the output. However,
if you select to output just a single setting with the C<--setting> option
followed by a setting name, newlines in it's value will B<not> be converted.
