+*
+*   raylib - A simple and easy-to-use library to enjoy videogames programming (www.raylib.com)
+*
+*   FEATURES:
+*       - NO external dependencies, all required libraries included with raylib
+*       - Multiplatform: Windows, Linux, FreeBSD, OpenBSD, NetBSD, DragonFly, MacOS, UWP, Android, Raspberry Pi, HTML5.
+*       - Written in plain C code (C99) in PascalCase/camelCase notation
+*       - Hardware accelerated with OpenGL (1.1, 2.1, 3.3 or ES2 - choose at compile)
+*       - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
+*       - Multiple Fonts formats supported (TTF, XNA fonts, AngelCode fonts)
+*       - Outstanding texture formats support, including compressed formats (DXT, ETC, ASTC)
+*       - Full 3d support for 3d Shapes, Models, Billboards, Heightmaps and more!
+*       - Flexible Materials system, supporting classic maps and PBR maps
+*       - Skeletal Animation support (CPU bones-based animation)
+*       - Shaders support, including Model shaders and Postprocessing shaders
+*       - Powerful math module for Vector, Matrix and Quaternion operations: [raymath]
+*       - Audio loading and playing with streaming support (WAV, OGG, MP3, FLAC, XM, MOD)
+*       - VR stereo rendering with configurable HMD device parameters
+*       - Bindings to multiple programming languages available!
+*
+*   NOTES:
+*       One custom font is loaded by default when InitWindow() [core]
+*       If using OpenGL 3.3 or ES2, one default shader is loaded automatically (internally defined) [rlgl]
+*       If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
