		page-not-url - Set True|False for named tracking instead of url in Piwik interface, defaults to False
		page-name - Set the page name here, defaults to document.location. For a string, see example, otherwise javascript.
		site-id - Set the ID of the site you are tracking, defaults to 1 (main site)
		link-tracking - Set True|False for link tracking, defaults to True
		ignore-class - Classname to use on ignored links, Piwik will not track clicks on these links
		download-class - Classname to use for download links, Piwik will record a download
		link-class - Classname to use for external links, Piwik tracks external links anyway, set this to force external link tracking
