/**

* @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 kind of html).
|
||
* Otherwise the output will be constructed BBCode.
|
||
*
|
||
* @see ParseUrl::getSiteinfo() for more information about scraping embeddable content
