The combine utility is a general purpose utility to compare 2 or 3 ASCII files.
The output of the utility is either a report describing the differences
between the files or a file which is the composite of the original files.
The output report format of this utility is friendlier than the Unix diff
utility. The composite output file feature of this utility is unique in
its presentation of file differences.

The combine utility uses a fundamental comparison algorithm as described
in "A technique for Isolating differences between files";
Communications of the ACM; April 1978; Volume 21 Number 4.

The combine utility is being contributed to the public domain. The disclaimer
at the begining of each file is required by my employer (Harris Computer
Systems Division) to ensure that Harris is not liable in the event
of errors in the software.

The combine utility has been in use at HCSD for 5 years. It runs on
Harris HCX and GCX architectures (CX/UX 4.1) and a SUN 3/160
(SUNOS version 4.0),
