The pmd-linked engine is automatically loaded as an intermediate stack when the postmaster (pmd) is started (usually with the ovstart command).

The postmaster is automatically configured to route events through the pmd-linked engine with the local registration file:

UNIX	$OV_LRF/pmd.ecs.lrf
Windows NT	%OV_MAIN_PATH%\lrf\pmd.ecs.lrf
