Good. Learn something new every day :). I think that chapter wasn't
there the first time I read the CVS manual (getting longer ago every
day :).

I'll have to try this.

Well, I think I'm just doing manually what CVS does with branches and

Here's the process:

1) Unpack the vendor's version 1.0 distribution twice; one "clean"
   copy, one I will modify.

2) Make my modifications.

3) Run 'diff' to get a single diff file showing all my modifications.

Now, when Vendor version 2.0 comes along:

1) Unpack Vendor version 2.0 twice.

2) Run 'patch' to apply my version 1.0 changes to version 2.0.

3) Make more changes.

4) Run 'diff' to make a version 2.0 patch file.

This process is simpler than CVS when the vendor package is huge and
my local changes are small - a typical situation.
