(*) Amy can be comfortably run on Safari and Gecko-based browsers (Firefox, Camino, Seamonkey,...) on any OS. It's runnable on Internet Explorer 6,7 and Opera 9+, but it's not officially supported and user experience may not be pleasant. (**) Languages are supported through bundles. It's very easy to add support for your favorite language (and/or dialects). Currently implemented are C, C++, C#, JavaScript, Ruby (on Rails), PHP, Java, Texy and HTML.
