/**
* @file mod/parse_url.php
* @brief The parse_url module
*
* This module does parse an url for embedable content (audio, video, image files or link)
* information and does format this information to BBCode or html (this depends
* on the user settings - default is BBCode output).
* If the user has enabled the richtext editor setting the output will be in html
* (Note: This is not always possible and in some case not useful because
* the richtext editor doesn't support all ind of html).
* Otherwise the output will be constructed BBCode.
*
* @todo https://developers.google.com/+/plugins/snippet/
