.if false
	Mnemonic:	troff.im
	Abstract:	This file provides macros allowing {X}fm source to generate
				troff input from {X}fm source when the doc is passed through
				tfm, and to generate postscirpt output when passed through 
				pfm. About the only real use of this is to be able to maintain
				manual pages in the more easily read {X}fm source format.

		Some roff information was gleanded from this page:
