local addon = select(2,...)

--[[
Here's the control flow:
(1) This file or another addon calls :register_boss_mod("Foo",register[,unregister])
(2) When OL decides it's time to register with a boss mod, it calls
       register (addon, addon_do_boss)
    which should do whatever's needed.  This may happen more than once, if OL
    is turned on/off, etc.
(2b) If a boss mod is already in place,
       unregister (addon)
    will be called first, if such a function was given at the start.
(3) When the boss mod triggers a callback, this code should call
       addon_do_boss (.....)
    with the crapton of data passed as in the DBM-related code below.

NOTA BENE:
- 'register' will not be called multiple times in a row for the same boss mod.
- The callback for (3) must check if OL is appropriately active.
