I'm not sure if your question was rhetorical or not (I suspect it was), but for the record, it's a basic templating system for javascript and java like what most web frameworks have. You write a template with parameters ("hello $name") and basic commands ("{foreach $foo in $foolist} ..."). Then in your code you can parameterize the template with data ({name: "benatkin", foolist: [...]}) and it'll get expanded.
