[xwiki-users] FW: Scheduler

Hi All, A few queries that I've split up to make it easier to make use of in Nabble for future reference. 1) What language is used in the scheduler script? I would assume it's running either velocity or groovy within the xwiki engine? 2) Are $xwiki and $context available to the script? 3) Is there feedback in the event of an error (like in a logfile or something)? 4) Is there a timeout associated to the script that runs, and are there any permission restrictions on adding the scheduler if it's going to be modifying document objects?
