Yeah, traditional way to do this is to give special markers around
what you want your Makefile to tell you, e.g.

        sayit:
                echo "@@@ $(FOO) ###"
        useit:
                $(MAKE) sayit | \
                sed -ne 's/^@@@ \(.*\) ###$/\1/p' | \
                ... use it ...

but in this case we know we want "*.txt", so the way you filtered
the output is sufficient.

Yay, maintainability comes with a large line reduction bonus ;-)

Thanks.
