	maybe not very relevant but i should mention...

	"magicpoint" presentation tool includes postscript file generator
	mgp2ps, and works great for both presentation-with-pc and generating
	postscript output.
	the input file is simple dumb plaintext (even dumber than lout).
	no math nor table support, but can invoke external commands from
	presentation foil.

	available at pkgsrc/graphics/magicpoint.
