<?php
/**
 * Code modified by Wynter Woods for Windowpane.
 * Uses a LessPHP rather than the original Ruby LESS.
 * This allows less files to be compiled on the fly by
 * any server supporting PHP, and removes the Ruby
 * requirement.
 *
 * There is a caveat to this, which is documented at
 * the LessPHP site: http://leafo.net/lessphp/docs/
