<p>This <strong>Browser</strong> compatibility layer extends core CoffeeScript functions
to make things work smoothly when compiling code directly in the browser.
We add support for loading remote Coffee scripts via <strong>XHR</strong>, and
<code>text/coffeescript</code> script tags, source maps via data-URLs, and so on.</p>
