+# mdd importer by Bill L.Nieuwendorp
+# conversion to blender 2.5: Ivo Grigull (loolarge)
+#
+# Warning if the vertex order or vertex count differs from the
+# origonal model the mdd was Baked out from their will be Strange
+# behavior
+#
+# vertex animation to ShapeKeys with ipo  and gives the frame a value of 1.0
+# A modifier to read mdd files would be Ideal but thats for another day :)
