Are there any plugins for eclipse that add syntax highlighting and other niceties for editing Haml and Sass? Google searches only seem to point to a dead project on lucky-dip.net.

Note: it's Sass I'm most interested in. A solution for using just Sass (or something similar to it like less) in Eclipse would suit my needs.

Also, I'm developing for Google App Engine (Java), using the App Engine plugin for Eclipse. So switching to another IDE isn't an option.

Update: So I've got syntax highlighting now using Pascal's answer and I've installed Ruby and Compass to compile sass into css.

However I'm aware that the syntax of sass will be changing with 2.4 so I'd still like to get the Haml and Sass Editors that come with Aptana to work. When I tried to use them they threw an exception and wouldn't display the files. I'd be interested to know if that's because I misconfigured Aptana or is an actual bug in the editors.

I'd also be very interested in any way of compiling Sass that integrated with Ecplise so that I didn't have to run something separate from it. (or a way of putting Sass/Compass in the Ecplise build process.)
