I've looked a bit at that, there's also a nice gallery with code examples on their web site. I drawback is that you cannot simply apt-get install it, you need a newer version, meaning manual install, and that pretty much always means a lot more work than anyone will admit since Linux environments can be set up in so may ways. But I'll give it a try, cant find any better option right now.
