By aspiers:

-1 is not a sensible debug level. The idea is to choose debug levels between 0 and 10 so that the user can control how much verbosity they get; 0 means very quiet and 10 means extremely verbose. So a low number should only be used for more important messages which occur less frequently, and high numbers for less important messages which occur more frequently.
