From: "John M. Sellens" <jmsellens> man page includes a list of valid types with no explanation, and those are only those types that were valid on math at the time that the help.out was created (which the source Makefile doesn't seem to update automatically, so it could be long out of date), which is before the last time the man page was formattted.
