Handy little script.

Yeah, that would be great, so you can add a bit of a description in
the commit message.

Did you take a look at my pacsearch script? That does some sort of
intelligent matching of package versions.

Just spell out "Example"? We can afford a few more bytes. :)

Not exactly cheap as you have to do two grep calls for every package
you list. Perhaps cmp or diff could be used?

And now for the real off-the-wall suggestion- doing this in perl would
give you the power of regular expressions and probably make this all
real easy. That is if you can figure out perl.
