Help Autosac

Syntax:  autosac

This command sets your preference to automatically sacrifice corpses when
you kill a monster.  If you are a vampire with autoconsume on, this will
consume the corpse instead, rather than sacrificing it.  If '
autoloot' is
turned on, you will only sacrifice empty corpses.

If this setting is toggled off, you may still manually sacrifice a corpse
with the '
sacrifice' command.

Note- if all of autoloot, autogold, and keyloot are off, this will 
sacrifice a monster's corpse regardless of what is in it.
