Introduction

We are planning to move away from CMT as our build tool in favor of a the more flexible SCons.  What is SCons?  "SCons is an Open Source software construction tool---that is, a next-generation build tool. Think of SCons as an improved, cross-platform substitute for the classic Make utility with integrated functionality similar to autoconf/automake and compiler caches such as ccache. In short, SCons is an easier, more reliable and faster way to build software." - http://scons.org/
