			There are extra fonts available in the plotutils package.
			The current ebuild does not install them for you since most
			of them can be installed via the media-fonts/urw-fonts
			package. See /usr/share/doc/${PF}/INSTALL.fonts for
			information on installing the remaining Tektronix fonts.

			If you manually install the extra fonts and use the
			program xfig, you might want to recompile to take
			advantage of the additional ps fonts.
			Also, it is possible to enable ghostscript and your
			printer to use the HP fonts.
