+    (description
+     "This package provides a LADSPA plugin for a four-band parametric
+equalizer.  Each section has an active/bypass switch, frequency, bandwidth and
+gain controls.  There is also a global bypass switch and gain control.
+
+The 2nd order resonant filters are implemented using a Mitra-Regalia style
+lattice filter, which is stable even while parameters are being changed.
+
+All switches and controls are internally smoothed, so they can be used 'live'
+without any clicks or zipper noises.  This makes this plugin suitable for use
+in systems that allow automation of plugin control ports, such as Ardour, or
+for stage use.")
