+     "The DOSBox Staging project attempts to modernize DOSBox.
+
+DOSBox emulates an Intel x86 personal computer running an IBM PC compatible disk
+operating system (@dfn{DOS}) in both real and protected modes.  It was primarily
+designed to run old DOS games, but aims to be fully compatible with all DOS
+programs and replicate the experience as accurately as possible.
+
+This fork fixes some perceived issues with DOSBox and adds new features such as
+Wayland support, PowerPC/POWER dynamic recompilation, and FluidSynth MIDI.
+Other features may be removed: for example, physical CDs can no longer be
+played, only emulated media.
+
+Graphical emulation includes contemporary text mode, Hercules, CGA, EGA, VGA,
+VESA, S3@tie{}Trio@tie{}64, and Tandy hardware.
+
+Emulated legacy sound devices range from a rudimentary `PC speaker' buzzer to
+the once state-of-the-art Gravis Utrasound sampling sound card.  The default is
+a SoundBlaster 16 providing 16-bit stereo sound.  MIDI is forwarded to the host
+through an emulated MPU-401.
+
+An emulated hardware modem is also included, letting one host or dial a
+@acronym{BBS, Bulletin Board System} across the Internet, network over IPX, and
+emulate a serial nullmodem over TCP/IP.")
