+ "This package provides various LADSPA plugins. @code{cs_chorus} and
+@code{cs_phaser} provide chorus and phaser effects, respectively;
+@code{mvclpf24} provides four implementations of the low-pass filter used in
+vintage Moog synthesizers; @code{mvchpf24} is based on the voltage-controlled
+high-pass filter by Robert Moog. The filters attempt to accurately emulate
+the non-linear circuit elements of their original analog counterparts.")
