=head1 restart-server.pl
Restarts one of the servers managed by Virtualmin.
This command stops and re-starts one of the servers managed by Virtualmin,
such as Apache or BIND. The server to restart must be set using the
C<--server> flag, followed by a feature name like C<web> or C<dns>.
For server types that have multiple versions such as FPM, you can select
the version to restart with the C<--version> flag. Or use C<--domain> to find
automatically select the correct version for the given domain.
