When making a few changes to a program's source code, for
example, to get an Open Source program to build on your system,
it's easy to forget what you've changed. You can use a source
code change control system such as RCS or CVS, but that's a lot
of baggage when you're just making a few changes here and
there. Setbase keeps track of files you've
changed using standard Unix utilities so when you go to install
a newer version, you needn't start from scratch and fix the
same things all over again.
