+ REVISION HISTORY
+
+ Description: Changed file name to bitreorder_tab.c and .h. Also, updated the
+              module description.
+
+ Description: Define "const Word16 *reorderBits[NUM_MODES-1]" as
+              "const Word16 *const reorderBits[NUM_MODES-1]".
+
+ Description: Added #ifdef __cplusplus and removed "extern" from table
+              definition. Removed corresponding header file from Include
+              section.
+
+ Description: Put "extern" back.
