+/*! \class ReedTabl
+    \brief STK reed table class.
+
+    This class implements a simple one breakpoint,
+    non-linear reed function, as described by
+    Smith (1986).  This function is based on a
+    memoryless non-linear spring model of the reed
+    (the reed mass is ignored) which saturates when
+    the reed collides with the mouthpiece facing.
+
+    See McIntyre, Schumacher, & Woodhouse (1983),
+    Smith (1986), Hirschman, Cook, Scavone, and
+    others for more information.
+
+    by Perry R. Cook and Gary P. Scavone, 1995 - 2002.
