SUBSTITUTIONS
@osuccess, @ofail and @odrop messages may contain %-substitutions, which
evaluate to gender-specific pronouns if the player's gender is set. They
are: %s (subjective) = Name, he, she, it. %o (objective) = Name, him, her, it.
%p (possessive) = Name's, his, her, its. %n (player's name) = Name.
%a (absolute possessive) = Name's, his, hers, its.  %r (reflexive) = Name,
himself, herself, itself.  If you need a '%', use %%. If you want the
pronoun to be capitalized, use a capital letter for the substitution, like
%S, %P, and so on.  Example: '@ofail teapot=burns %p hand on the hot
teapot.  %S screams in agony.  Hot water spills on %o, and %s whimpers
to %r that %s should be more careful in the future.' See GENDER.
