Eric S. Raymond <esr at snark.thyrsus.com>; reworked,
reorganized, and massively rewrote Chin Fang's original in an attempt
to understand it. In the process, he merged in most of a different
how-to by Bob Crosson <crosson at cam.nist.gov>.
Payne Freret <payne at freret.org> corrected some
minor technical errors about monitor design.
Martin Lottermoser <Martin.Lottermoser at mch.sni.de>
contributed the idea of using gnuplot to make mode diagrams and did
the mathematical analysis behind modeplot. The
distributed modeplot was redesigned and generalized
by ESR from Martin's original gnuplot code for one case.
