+ * MDR is being used in EliteForce, JediKnight2 and Soldiers of Fortune2 (I think).
+ * So this comes in handy for anyone who wants to make it possible to load player
+ * models from these games.
+ * This format has bone tags, which is similar to the thing you have in md3 I suppose.
+ * Raven has released their version of md3view under GPL enabling me to add support
+ * to this codebase. Thanks to Steven Howes aka Skinner for helping with example
+ * source code.
