+	optional argument to define the dimension along which to perform
+	the differences and allow the order of the differences to be larger
+	than the dimension itself.
+
+	* general/rotdim.m: New function for rotation of an N-d array in an
+	arbitrary plane.
+
+	* general/flipdim.m: New function to flip an N-d array about an 
+	arbitrary axis.
+
+	* general/rot90.m, general/fliplr.m, general/flipud.m: Limit the
