+// CLASS DESCRIPTION (MPxDeformerNode)
+//
+// MPxDeformerNode allows the creation of user-defined deformers.  A deformer
+// is a node which takes any number of input geometries, deforms them and
+// places the output into the output geometry attribute.
+//
+// For more information, please see the built-in documentation
+// in MPxDeformerNode.cpp.
