which           which [object-type] thing-to-match.  This command shows
                you what things match you query. For example, if you have
                a player named "Igor The Ferret" and an object called 
                "ferret chow", a "which ferret" will show you both matches
                and their object ids. A "which object ferret" will only
                show the "ferret chow", however. Since the look command
                does not show object ids after the names of things you
                own, the 'which' command is the quickest way to find out
                the number of any particular object.
