+sdl2trs (Radio Shack TRS-80 Model I/III/4/4P Emulator)
+
+sdl2trs is a Radio Shack TRS-80 Model I/III/4/4P emulator for
+Macintosh OSX, Windows and Linux. It has been ported from the
+excellent X Window Unix emulator xtrs. Instead of using the X-Window
+system for graphics, it uses the portable SDL library.
+
+This build uses SDL-2.0, which is designed for newer machines. If you
+have an older machine, or if sdl2trs doesn't perform well on your
+system, try the SDL-1.2 version, sdl2trs. It's possible to install
+both sdl2trs and sdl2trs on the same system with no conflicts.
+
+Note: When you start up sdl2trs for the first time, it attempts
+to boot from floppy disk. If you didn't give either the "-disk0
+/path/to/image.dsk" or "-nofloppy" options on the command line, it
+will "hang" with a black screen, because it's trying to boot from a
+nonexistent floppy disc. To recover from this:
+
+- Hold down F10 (TRS-80 Reset) and press Escape (TRS-80 Break key) to
+  skip the disk boot and enter the ROM BASIC.
+
+- Press Alt+D to enter the emulator's disk menu, and from there,
+  either select a bootable disk image for drive 0, or disable the
+  floppy disk controller. Then press Shift-F10 to reboot the TRS-80.
+
+See the man page and the documentation at
+/usr/doc/sdl2trs-$VERSION/html/index.html for further details.

+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
