pf.ps
	Prints a sheet per font with all glyphs the font contains. If
	a font F is not printer resident, you have to include it in the
	file before calling /F showfont. The font has got to be in
	ASCII form; if it is in binary form on your disk, you've got to
	use pfbtops to convert it. pfbtops can be found in groff-1.08
	or higher.
