   This yields a linear gradient spanning from left to right

   This yields a linear gradient starting at white passing

  // Firefox's gradient api is nice.
     Webkit's gradient api sucks -- hence these backflips:
  $end: grad_opposite_position($start)
  background-image: -webkit-gradient(linear, #{grad_point($start)}, #{grad_point($end)}, #{grad_color_stops($color_stops)})
  background-image: -moz-linear-gradient(#{$start}, #{$color_stops})

// Due to limitation's of webkit, the radial gradient mixin works best if you use
   pixel-based color stops.
  
   Examples:
  
       // Defaults to a centered, 100px radius gradient
       +radial-gradient(color_stops(#c00, #00c))
       // 100px radius gradient in the top left corner
       +radial-gradient(color_stops(#c00, #00c), "top left")
       // Three colors, ending at 50px and passing thru #fff at 25px

unable to parse indent due to sass-convert multi-line comment conversion, comment starting the file, and first indented line having 3 spaces that were originally guarded by their own //. i could see this happening a lot when a file starts with a comment.
