Debugger-Hook names a function, with lambda list (CONDITION MYSELF-ISH):
Handle an unhandled error in Production.
If TOOTSVILLE *VERBOSE-BUGS* is set, a private admin message is sent to the client identified by it with the condition text and a stack backtrace.
The condition goes to the VERBOSE::ERROR (not in this manual) logging.
The condition and backtrace go to *ERROR-OUTPUT* (see the Common Lisp HyperSpec).
Calls ROLLBAR DEBUGGER-HOOK to report the condition to Rollbar.
Falls through to any other *DEBUGGER-HOOK* (see the Common Lisp HyperSpec) that may exist.
