+*
+*   raylib [rlgl] example - Using rlgl module as standalone module
+*
+*   NOTE: This example requires OpenGL 3.3 or ES2 versions for shaders support,
+*         OpenGL 1.1 does not support shaders but it can also be used.
+*
+*   Compile rlgl module using:
+*   gcc -c rlgl.c -Wall -std=c99 -DRLGL_STANDALONE -DRAYMATH_IMPLEMENTATION -DGRAPHICS_API_OPENGL_33
+*
+*   Compile example using:
+*   gcc -o $(NAME_PART).exe $(FILE_NAME) rlgl.o glad.o -lglfw3 -lopengl32 -lgdi32 -std=c99
+*
+*   This example has been created using raylib 1.5 (www.raylib.com)
