    LESS Prefixer
  ---------------------------------------------------
    
    All of the CSS3 fun, none of the prefixes!

    As a rule, you can use the CSS properties you
    would expect just by adding a '.':

    box-shadow => .box-shadow(@args)

    Also, when shorthand is available, arguments are
    not parameterized. Learn CSS, not LESS Prefixer.
