+/*! \class Sitar
+    \brief STK sitar string model class.
+
+    This class implements a sitar plucked string
+    physical model based on the Karplus-Strong
+    algorithm.
+
+    This is a digital waveguide model, making its
+    use possibly subject to patents held by
+    Stanford University, Yamaha, and others.
+    There exist at least two patents, assigned to
+    Stanford, bearing the names of Karplus and/or
+    Strong.
+
+    by Perry R. Cook and Gary P. Scavone, 1995 - 2005.
