	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.  This allows the more easily read {X}fm source to be used
				to generate man pages, and to be able to generate the man pages
				in various output formats (txt, rst, etc.).

	Author:		E. Scott Daniels
	Date:		27 January 2019

		Some roff information was gleanded from these pages:
			http://cmd.inp.nsk.su/old/cmd2/manuals/unix/UNIX_Unleashed/ch08.htm
			https://www.gnu.org/software/groff/manual/html_node/Basics.html

.** assume that we're generating roff output when tfm is used. These macros
.** convert {X}fm input into troff.
