;; The *entity-info* table contains some simple information that can be used to
;; spawn a process for an entity.
;;   :ptype     the type of the process
;;   :package   the package that must be loaded (not used?)
;;   :art-group the art that must be loaded
;;   :pool      the pool that the process should be allocated from
;;   :heap-size the required size for the process heap

;; At one point, this was much bigger, but got smaller between
;; the demo and final build.  The entity info is possibly stored somewhere else
;; and this may not even be used.
