Package extensions usage

[Kenneth Tilton]

Packages are over-rated. We lived (and suffered) with packages for months
and when I finally rolled everything up into one package it presented zero
problems and ended a steady stream of problems. As one Lisp venerable said,
"It was a package problem. It is always a package problem."
