+     "Rakarrack is a richly featured multi-effects processor emulating a
+guitar effects pedalboard.  Effects include compressor, expander, noise gate,
+equalizers, exciter, flangers, chorus, various delay and reverb effects,
+distortion modules and many more.  Most of the effects engine is built from
+modules found in the excellent software synthesizer ZynAddSubFX.  Presets and
+user interface are optimized for guitar, but Rakarrack processes signals in
+stereo while it does not apply internal band-limiting filtering, and thus is
+well suited to all musical instruments and vocals.")
