-1. Fork this Root Gist to create a new snippet.
-2. Modify your gist according to following rules:
-  1. **You MUST put a gist description** which summarizes your snippet as precisely as possible:
-     * Words starting with `#` like `#tag` are indexed as hashtags.
-     * Words starting with `@` like `@john` are highlighted as Twitter links (You can also precise `@twitter:john` or `@github:john`
-     * URL will be highlighted in the description
-  2. You can add as many files as you want in your gist
-  3. File extensions are used to identify the language (e.g. `code.scala` -> scala)
-  4. A code snippet shouldn't be too long (a few lines if possible) so don't hesitate to cut in several files
-  5. If you want to explain precisely your code or provide usage examples, please use a Markdown file (e.g. `README.md`)
-  6. You can put a License in `__LICENSE.txt` case your code need to be protected in anyway
-  7. You can delete `_README.md` and any modification in it isn't taken into account
-3. Save it & wait for [Play Xamplez](http://play.xamplez.io) to index it.
