According to my experience, normal users don't care whether
the stuff is technically a bitmask or a level. Usually they
like to provide one single full debug log file using just the
maximum bitmask or level and leave the rest to the experts.
Therefore I prefer bitmasks provided that the debug output has
appropriate identifiers for each kind of message so that one can
easily "grep" for certain kind of messages in a debug log file.
