      3 *   raylib v5.1-dev - A simple and easy-to-use library to enjoy videogames programming (www.raylib.com)
      4 *
      5 *   FEATURES:
      6 *       - NO external dependencies, all required libraries included with raylib
      7 *       - Multiplatform: Windows, Linux, FreeBSD, OpenBSD, NetBSD, DragonFly,
      8 *                        MacOS, Haiku, Android, Raspberry Pi, DRM native, HTML5.
      9 *       - Written in plain C code (C99) in PascalCase/camelCase notation
     10 *       - Hardware accelerated with OpenGL (1.1, 2.1, 3.3, 4.3 or ES2 - choose at compile)
     11 *       - Unique OpenGL abstraction layer (usable as standalone module): [rlgl]
     12 *       - Multiple Fonts formats supported (TTF, XNA fonts, AngelCode fonts)
     13 *       - Outstanding texture formats support, including compressed formats (DXT, ETC, ASTC)
     14 *       - Full 3d support for 3d Shapes, Models, Billboards, Heightmaps and more!
     15 *       - Flexible Materials system, supporting classic maps and PBR maps
