5. It uses GNU Autoconf scripts for compiling the part of the Tclkit
	   that brings the whole thing together (the Kitsh)

To accomplish these goals the following mechanisms are in place:
	1. The top-level "kitcreator" script; and
	2. Per-project subdirectories, each containing a "build.sh" script

The top-level "kitcreator" script is very simple.  It's only job is to
interpret command line arguments, and call the per-project "build.sh" scripts.
For the "tcl" project it also finds the appropriate "tclConfig.sh" (and stores
this path in TCLCONFIGDIR) to enable subsequent build scripts to find the
appropriate Tcl to link against.

The per-project "build.sh" scripts are entirely autonomous.  They are
responsible for downloading the source code for the appropriate version that
