61=head2 OBJECT EVENTS
62
63Object events always relate to a specific object, which is always the

66
67=head3 add_bonus (item creator difficulty max_magic flags -- )
68
69A basic item has been created (e.g. for shops, monsters drops etc.)
70that needs bonus values applied. The B<creator> object is a template
71object that can be used to inherit stuff (and can be NULL). Flags is a
72combination of GT_ENVIRONMENT (???) or GT_STARTEQUIP (set FLAG_STARTEQUIP
73on item or set its value to 0) or GT_MINIMAL (???)
74
75When overriden, built-in bonus generation is skipped, otherwise
76treasure generation continues as it would without this hook.
77
78In general, if flags != 0 or creator != 0 you should just return and leave
79item generation to the standard code.
