 Runs the recess compiler to rebuild the `/less` files and compiles the docs pages. Requires recess and uglify-js. <a href="http://twitter.github.com/bootstrap/less.html#compiling">Read more in our docs &raquo;</a>
 
++ **test** - `make test`
+Runs jshint and qunit tests headlessly in phantom js (used for ci). Depends on having phatomjs installed.
