There is an irrelevant link in Help, FAQ.

Sentence:
You can write hawtio plugins in anything that runs in a browser and ideally compiles to JavaScript. So use pure JavaScript, CoffeeScript, EcmaScript6-transpiler, TypeScript, GWT, Kotlin, Ceylon, ClojureScript, ScalaJS and any language that compiles to JavaScript.

Link "any language that compiles to JavaScript" should point to some relevant page. But it points to altjs.org and this is redirected to http://wrsouthshore.com/ and this is not correct.
