/*
* TODO:
* - find a way to use the same string as in the @include lines to match the
* current window.location. Look for something like GM_testUrl() which builds
* the regexp starting from a glob line.
- * - use xpath instead of regexp like in http://a32.me/2009/11/greasemonkey/
* - use jquery, like shown in http://a32.me/2009/11/greasemonkey/
+ * - Support the "download" attribute for anchors:
+ * http://www.whatwg.org/specs/web-apps/current-work/multipage/links.html#downloading-resources
*/
/* Fields supported by the "site" object.
*
* Manadatory fields:
- * pageURL: the URL of the page we are modifying
- * urlContainer: the element containing the URL to link
+ * locationRegExp: the regexp describing the URL of the page we are modifying
+ * urlContainerXPath: the XPath of the element containing the URL to link
* urlRegexp: the regular expression for finding the URL, the first
* sub-pattern is taken as the URL
- * linkDest: the element where to place the Direct Download link
+ * linkDestXPath: the XPath of the element where to place the Direct Download link
*
*
* Optional fields:
+ *
+ * initCommand: a function called before the regExp is matched, this can
+ * be useful in cases when some action needs to be done in
+ * order to make the element containing the regExp be actually
+ * rendered. It must accept a 'site' parameter.
+ *
* onEvent: used to delay the urlRegexp matching to a certain event like
* 'DOMNodeInserted' useful when the URL is added by some javascript
* library. It has two fields:
