Syntax highlighting support for Scheme language in Brackets editor (http://brackets.io/) (Should work with Racket and other variants too.)
Brackets for some reason only support these languages: https://github.com/adobe/brackets/blob/master/src/language/languages.json despite CodeMirror that Brackets use is supporting many more.
Fortunately, it's easy to add support for those through an extension: https://github.com/adobe/brackets/wiki/Language-Support#defining-a-new-language and that's why and how this extension has been created.
