-*   Physac - Body shatter
+*   raylib [physac] example - physics shatter
 *
-*   NOTE 1: Physac requires multi-threading, when InitPhysics() a second thread is created to manage physics calculations.
-*   NOTE 2: Physac requires static C library linkage to avoid dependency on MinGW DLL (-static -lpthread)
+*   This example has been created using raylib 1.5 (www.raylib.com)
+*   raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
 *
-*   Use the following line to compile:
+*   This example uses physac 1.1 (https://github.com/raysan5/raylib/blob/master/src/physac.h)
 *
-*   gcc -o $(NAME_PART).exe $(FILE_NAME) -s -static  /
