 Complete raylib LUA binding. All raylib functions plus the +60 code examples have been ported to LUA, now LUA users can enjoy coding videogames in LUA while using all the internal power of raylib. This addition also open the doors to LUA scripting support for a future raylib-based engine, being able to move game logic (Init, Update, Draw, De-Init) to LUA scripts while keep using raylib functionality.
 
-Completely redesigned audio module. Based on the new direction taken in raylib 1.5, it has been further improved and more functionality added to allow raw audio processing and playing. FLAC file format support has also been added. In the same line, OpenAL Soft backend is now provided as a static library in Windows to allow static linking and get ride of OpenAL32.dll. Now raylib Windows games are completey self-contained, no external libraries required any more!

 Camera and gestures modules have been reviewed, highly simplified and ported to single-file header-only libraries for easier portability and usage flexibility. Consequently, camera system usage has been simplified in all examples.

 Build system improvement. Added support for raylib dynamic library generation (raylib.dll) for users that prefer dynamic library linking. Also thinking on advance users, it has been added pre-configured Visual Studio C++ 2015 solution with raylib project and C/C++ examples for users that prefer that professional IDE and compiler.
 
 New examples, new functions, complete code-base review, multiple bugs corrected... this is raylib 1.6. Enjoy making games.

+*   Physac - 2D Physics library for videogames
 *
-*   // TODO: Description...
+*   Description: Physac is a small 2D physics engine written in pure C. The engine uses a fixed time-step thread loop 
+*   to simluate physics. A physics step contains the following phases: get collision information, apply dynamics, 
+*   collision solving and position correction. It uses a very simple struct for physic bodies with a position vector 
+*   to be used in any 3D rendering API.
 * 
 *   CONFIGURATION:
 *   
@@ -24,30 +27,21 @@
 *       internally in the library and input management and drawing functions must be provided by
 *       the user (check library implementation for further details).
 *
+*   #define PHYSAC_DEBUG
+*       Traces log messages when creating and destroying physics bodies and detects errors in physics 
+*       calculations and reference exceptions; it is useful for debug purposes
+*
 *   #define PHYSAC_MALLOC()
 *   #define PHYSAC_FREE()
 *       You can define your own malloc/free implementation replacing stdlib.h malloc()/free() functions.
 *       Otherwise it will include stdlib.h and use the C standard library malloc()/free() function.
-*       
-*   LIMITATIONS:
-*
-*       - There is a limit of 256 physic objects.
-*       - Physics behaviour can be unexpected using bounciness or friction values out of 0.0f - 1.0f range.
-*       - The module is limited to 2D axis oriented physics.
-*       - Physics colliders must be rectangle or circle shapes (there is not a custom polygon collider type).
 *
-*   VERSIONS:
-*
-*   1.0 (14-Jun-2016) New module defines and fixed some delta time calculation bugs.
-*   0.9 (09-Jun-2016) Module names review and converted to header-only.
-*   0.8 (23-Mar-2016) Complete module redesign, steps-based for better physics resolution.
-*   0.3 (13-Feb-2016) Reviewed to add PhysicObjects pool.
-*   0.2 (03-Jan-2016) Improved physics calculations.
-*   0.1 (30-Dec-2015) Initial release.
