This directory contains Fred Fish' internal debugging package DBUG.

The original files are

	dbug.c		code for the debugging library
	dbug.h		header file for debugged programs
	dbug.p		documentation for the library

To these I have added

	Makefile	builds dbug.o and the sample program
	Readme		this file!
	dbug.qr		a quick reference sheet for the library
	fact.c		the sample program from the documentation

the make targets are

	all (default)	dbug.o and fact
	dbug.o		the debugging library, ready for linking
	fact		the sample program, linked and ready to test-drive

I highly recommend this package. It is configurable at run time, allowing
the debugging trace to be limited, for example, to selected functions and/or
types of operation. If used widely, it also guarantees a consistent debugging
interface across different programs. It is in the public domain (see the
header comment in dbug.[ch] for details).
