This is a boss mod plugin for Deadly Boss Mods. It makes 8 outdoor creatures into "bosses" for purposes of testing DBM callbacks with other addons. Once you register your addon with DBM you can engage one of these creatures in combat to exercise all the same code paths but without the inconvenience of, you know, potential death.
The eight outdoor creatures are around level 6 or 7. There is one creature per capital city, chosen to be near the entrance to that capital. The goal was to be able to easily test addons by teleporting to a capital and then reaching the test site quickly, maybe even using a bank alt to do the tests. :-)
If you are not developing an addon, this will do nothing useful (but it's very flattering finding it included in half a dozen UI compilations...). If you are developing an addon, this addon will still do nothing useful unless loaded manually by code in your own addon. Instructions and functioning sample code are in the file README.TXT, unpacked into the usual place.
