	Abstract:	This file provides macros allowing {X}fm source to generate
				rts input from {X}fm source when the doc is passed through
				tfm, and to generate postscirpt output when passed through
				pfm. Simalar to the roff.im macro set that allows the generation
				of troff input for man pages.

	.** convert {X}fm input into rts.
	.** post processing is needed to strip the leading space that tfm insists on adding.

	.** bloody rst has no consistant marking character, and each header level must be different and as long as the text.
	.** and of course they don't generate <hx> tags in the resulting HTML, but <section> tags. WTF?
