Grunt

Hi, I have created a configuration file for grunt. 

http://gruntjs.com/

Added there a couple of useful rules:
- Concatenation of all the src / *. Js files into one
- Minimize the glued file
- The call syntax checking jshint (as yet no specific rules)

The plans to make a test call and generate documentation in markdown format, and html.

I think that this is not such an important functionality for that would get the new version, but it's utility seriously make life easier for all js developers.

Sorry for my english :-|
