Erik Walthinsen a80b0c26d5 Added DEBUG, INFO, and ERROR systems. Very little code is converted yet.
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.
