cockpit.message()

message = cockpit.message(problem)
message = cockpit.message(exception)

Return a message for the exception or problem code passed as an argument. If the argument is an object with a "message" property, as is the case with most exceptions, that will be returned directly. If the argument is an object with a "problem" property, then it will be used as the problem code. An appropriate message will be returned for problem codes.
