Once a necromancer has gained some measure of control over undead, he may
allow those undead (and certain other minions) to feed from corpses,
butchered meat and even caught fish if they are large enough.

This is a quick way to help both raised and controlled undead regenerate,
should they suffer serious damage.

To order your minions to consume corpses or meat, use the 'control'
command.  For example:

control vampire consume corpse
control all consume corpse

In addition to raised undead, skeletons, the flesh beast, and the bone
guardian may also consume corpses and meat.  Raised undead gain greatly
from consumption, but skeletons and animated creatures may only get
limited value from it.
