Now examples can be compiled by module, that's useful when compilation fails at some point

 ### raylib philosophy
 
  - raylib is a tool to enjoy videogames programming, every single function in raylib should be a tutorial on itself.
  - raylib is SIMPLE and EASY-TO-USE, I tried to keep it compact with a small set of functions, if a function is too complex or is not clearly useful, better not to include it.
  - raylib is open source and free; educators and institutions can use this tool to TEACH videogames programming completely by free.
- - raylib is collaborative; contribution of tutorials / code-examples / bugs-solving / code-comments are highly appreciated.
+ - raylib is collaborative; contribution of tutorials / code examples / bug fixes / code comments are highly appreciated.
  - raylib's license (and its external libs respective licenses) allow using it for commercial products.

-*   This example has been created using raylib 1.4 (www.raylib.com)
+*   raylib can load fonts from multiple file formats:
+*
+*     - TTF/OTF > Sprite font atlas is generated on loading, user can configure
+*                 some of the generation parameters (size, characters to include)
+*     - BMFonts > Angel code font fileformat, sprite font image must be provided
+*                 together with the .fnt file, font generation cna not be configured
+*     - XNA Spritefont > Sprite font image, following XNA Spritefont conventions,
+*                 Characters in image must follow some spacing and order rules 
+*
+*   This example has been created using raylib 2.6 (www.raylib.com)

-*   raylib [text] example - Font loading and usage
+*   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).
