The third degree of Freemasonry and the rigorous procedures to advance to that level. The term may have been coined by nineteenth century New York City Police detective Thomas F.

!BugGrabber is a small addon that simply grabs all Lua errors generated by WoW and makes them available to you through the /buggrabber slash command. Regular users should not use !BugGrabber. It is not designed to silence Lua errors - you can do that yourself from the Blizzard interface options. !BugGrabber is for developers. However, if you want to provide the developers of your favorite addon with useful bug reports, installing !BugGrabber and BugSack would be sensible. For casual developers, addons like BugSack can interact with !BugGrabber to provide high level display interfaces for the captured errors.
