afio - extract single files?

[Tom Betz]

The discussion of multiple-tape cpio archives prompted me to
recommend afio, which defaults to writing cpio-compatible tape
archives, but then it occurred to me that cpio would be unable
to recognize an afio-created archive with more than one tape.

And then i went to try to figure out how one would extract just
one file from an afio-created archive, and realized that I don't
know how!

How does one do that?

Seems like something i should be able to do...
