 Synopsis:           Bindings for the ALSA sequencer API (MIDI stuff)
 Description:
   Bindings for the ALSA sequencer API (MIDI stuff)
-  Since there is also
-      <http://code.haskell.org/alsa/>
-  which aims at a more complete interface to ALSA
-  we will no longer maintain this one.
   .
+  There are now the packages @alsa-pcm@ and @alsa-seq@
+  that aim at a more complete interface to ALSA.
+  Thus we will no longer maintain this package.
+  .
   See "Sound.ALSA.Sequencer.Play" for how to play Haskore songs in realtime via ALSA.
