+// This now uses the supposedly cross-platform libcdio to do the necessary
+// low-level CD twiddling we need that libsdl can't do currently. Jury is
+// still out on whether or not to make this a conditional compilation or not.
//
+// Comment this out if you don't have libcdio installed
+// (Actually, this is defined in the Makefile to prevent having to edit
+// things too damn much. Jury is still out whether or not to make this
+// change permanent.)
