+      (description
+       "mididings is a MIDI router/processor based on Python, supporting ALSA
+and JACK MIDI.  Features include:
+
+@itemize
+@item MIDI routing and filtering; filter events depending on their event type,
+  channel, note number, velocity, etc., and freely route them between an
+  arbitrary number of input and output ports.
+@item Modifying and converting MIDI events; transpose notes, apply velocity
+  curves, change controller values and ranges, or convert events to any other
+  MIDI event type. mididings also includes more complex functions like a
+  diatonic harmonizer, floating split points, latched notes, and more.
+@item Seamless switching between patches; set up different \"scenes\", each
+  with its own MIDI routing and processing, and switch between them at any time,
+  even while playing.  Switching scenes does not affect notes already held, and
+  does not result in dropouts or stuck notes!
+@item MIDI event monitoring, running external commands; print MIDI event data
+  to the console to help debugging your patches and configuring your MIDI
+  controllers.  In addition to its MIDI output, mididings can also execute shell
+  commands and send OSC or DBUS messages.
