title: Javascript build tool similar to Compass?
body: <p>I'm look for a build tool that behaves like Compass in that it watches a folder(s) and then concatenates, minifies and produces a single output file. I would like to be able to specify the order of the files using a config.</p>
  
  <p>I currently use CodeKit (<a href="http://incident57.com/codekit/" rel="nofollow">http://incident57.com/codekit/</a>) which does this perfectly. But I have had issues with the JSON config file in the past which has meant I lost which javascript files were included, and also the order.</p>
