=head1 NAME
sync_with_master
=head1 DESCRIPTION
sync_with_master is a helper binary for B<mmm_agentd>. It tries to sync up a (soon active) master with his peer (old active master) when the I<active_master_role> is moved. If the peer is reachable it syncs with the master log. If not reachable, syncs with the relay log.
