// Package.pp
//
// This file defines certain configuration variables that are to be
// written into the various make scripts.  It is processed by ppremake
// (along with the Sources.pp files in each of the various
// directories) to generate build scripts appropriate to each
// environment.
//
// This is the package-specific file, which should be at the top of
// every source hierarchy.  It generally gets the ball rolling, and is
// responsible for explicitly including all of the relevent Config.pp
// files.
