Original commit message from CVS: Added DEBUG, INFO, and ERROR systems. Very little code is converted yet. Policy decisions need to be made as to what kinds of cases get what kind of response, and what the default ERROR response should be. Right now it will print out all the information, then have gdb spew a stack trace.
