Several kinds of messages can be set on a container object; they are printed to various audiences at certain times whenever an attempt is made to use the container. The ones whose names begin with 'o' are always shown prefixed with the name of the player making the attempt and a single space character. The standard pronoun substitutions (with respect to the player) are made on each message before it is printed; see "help pronouns" for details.
