+*
+*   raylib [text] example - Sprite font loading
+*
+*   Loaded sprite fonts have been generated following XNA SpriteFont conventions:
+*     - Characters must be ordered starting with character 32 (Space)
+*     - Every character must be contained within the same Rectangle height
+*     - Every character and every line must be separated the same distance
+*     - Rectangles must be defined by a magenta color background
+*
+*   If following this constraints, a font can be provided just by an image,
+*   this is quite handy to avoid additional information files (like BMFonts use).
+*
+*   This example has been created using raylib 1.0 (www.raylib.com)
+*   raylib is licensed under an unmodified zlib/libpng license (View raylib.h for details)
