*)| Default_page of srv(*Like
*)Main_pagebut is not taken into account for computing which is the current page in the menu. Use it for example when there is no main page, but you want one of the subpages to be the default page for your subsite. The service you use as default page must appear another time in the subtree!| Not_clickable(*When you do not want the menu entry to be a link but you want subpages.

'res Lwt.tThis function allows one to wrap a service handler easily depending on whether certain information is available or not.
The first arguments provides that information (Some value) of not (None), the second argument is called just with two arguments when the information is not available (the two arguments are suggesting GET and POST parameters of a request). The third argument is called with that information if available and the parameters.
