Hello Jay,
Thanks, I've figured out the raco incantation beforehand. I should've
read more about the docs before asking.
One other question that slipped my mind before, about wildcards. Let's
take this example again:
(define *db* (make-theory))
(datalog *db*
;; shareholders
I would do "raco pkg update --clone datalog" from "$PLTHOME/extra-pkgs"

for a small database (5 gb). I'm running into some problems that I'd
appreciate your help with:
* Is there support for negating a subgoal? E.g: [1]
Get the names of employees who do not work on any project.
