Does anybody out there have a program that they are willing to donate to
the cause that does the following:
Whenever I am working on some project, my normal procedure is to
copy the existing stuff into a new directory, make whatever changes
I need to, and then diff that to see exactly what files I have
changed. I then use that diff to create a companion directory that
lives in the same filesystem as the original that has all the files
that are unchanged link to the original file. This way the only
files that take up space are the ones that are changed and I can
see what is different simply by looking at the ls -l. Usually I
make the changes in a different filesystem than the one things are
stored in, so I simply can't create the directory with links. I
need a nice general purpose thing to do this, so please don't
mention SCCS and the ilk. Has anyone done this? I don't like re-
creating the wheel.
