// @Mixin Retina Sprite Sass
// ======================================================
// This requires two folders full of *.png files, normal and then
// 2x resolution. Please ensure that they have the same number and names
// of files.
// I've written this based off other efforts on the web, but none did
// both background-images and a set of sprites automatically.
// Still very much a work in progress.

// To use see the bottom three lines.
