XPP documentation to create job/div tools?

Does documentation exist to create job and div tools? I searched through all the 8.4 PDFs I could find, and don't see anything related to job/div tools. If so, would you please point me to it?

I created a job tool to make a .ps file, and it works, but when the tool is run, I get a pop-up window with the name of the job tool in the title bar and nothing else. It disappears after a few seconds. It would be nice to turn it off, or make it more meaningful. Is this window an XPP default when a job/div tool is called?

 

Thanks,
