"The other nice thing about wdiff is that it was
already installed on my machine! About two (maybe three??) years
ago I googled around for something that would do diffs on text
files, but the searches only showed diff, kdiff etc. Wdiff
apparently dates back to the early 90s so my search terms maybe
weren't the best - or too many other people are using and linking
to diff! Anyway, wdiff seems to be part of the standard install for
OpenSuSE and I’d had it all along."
