+<longdescription>
+  xtrs is a Radio Shack TRS-80 Model I/III/4/4P emulator for Unix and the
+  X Window System. It includes lower case, the real time clock, hi-res
+  graphics, serial port, parallel printer, mouse, cassette, sound and music
+  output, 5" and 8" floppy disk drives in single and double density, and
+  even hard disk drives. The emulated floppy and hard disk file formats
+  are compatible with the popular MSDOS-based emulators by Jeff Vavasour,
+  Matthew Reed, and David Keil, and (if you choose a capable enough file
+  format), all features of the original TRS-80 floppy disk controller are
+  emulated. Under Linux, physical floppy disk drives are also supported.
+  Physical cassettes can be read and written too. The user interface is a
+  bit spartan, but it gets the job done.

+		\n\nxtrs -model 4p -diskdir /usr/share/xtrs
+		\n\nIf you already own a copy of the ROM software (e.g., if you have
+		a TRS-80 with this ROM), then you can make yourself a copy of this
+		for use with xtrs, using utilities available on the web. To load
+		your own ROM, specify the '-romfile' option, or the 'Xtrs.romfile'
+		X resource. ROM files can be in Intel hex or binary format."
