As Nigel mentioned this is e.g. documented in "Unix Text Processing", Dale Dougherty & Tim O'Reilly page 224 (available at http://www.oreilly.com/openbook/utp/). This is also documented in DWB3.3 doc/mm/PS.doc on page 31 (if the file is not there you need to run "./Run" in this directory (using the DWB troff path setting) to generate it).
