 The ``$link`` variable now contains an HTML formatted link for downloading the file. It also lists the file size next to the link.  You can use this variable anywhere that you create content for a page in your application. Notice that the last argument to the ``tripal_galaxy_get_proxy_url()`` function is the string ``download``.  This is the action that the proxy URL should perform.
