Kitsh Configure Options:
	1. --enable-kit-storage={zip|mk4|auto}
		Specify which type of storage to use with the Tclkit.  The
		default is to auto-detect.  Auto-detection uses Mk4 if
		available and built statically, otherwise it falls back to Zip.

Using the KitDLL SDK
--------------------
When you build a KitDLL, a "libtclkit-sdk-<tclvers>.tar.gz" tarball is also
produced.  This tarball contains the Tcl (and Tk, if compiled) stubs libraries,
and Tcl (and Tk, if compiled) header files needed to compile and link things
against Tcl (and Tk).  It also includes "tclConfig.sh" (and "tkConfig.sh", if
Tk was compiled).

The purpose for this tarball is to be used to build Tcl extensions or
applications that rely on Tcl/Tk using the KitDLL.

To use it, one first must extract the tarball.  After that the environment
variable "TCLKIT_SDK_DIR" must be set to the directory that was created in
order to make most of the variables contain useful values.

For example, to build an extension using the KitDLL SDK one would typically do
something like:
	1. Compile KitDLL (may be omitted if the KitDLL SDK is already
	   available)
		a. $ KITCREATOR_PKGS='tk itcl kitdll'
		b. $ export KITCREATOR_PKGS
		c. $ ./kitcreator
	2. Compile the Extension
		a. $ tar -xf /path/to/libtclkit-sdk-8.4.19.tar.gz
		b. $ TCLKIT_SDK_DIR="$(pwd)/libtclkit-sdk-8.4.19"
		c. $ export TCLKIT_SDK_DIR
		d. $ ./configure --with-tcl="${TCLKIT_SDK_DIR}/lib"
		e. $ make

Method of Operation

Summary:
	1. "kitcreator" calls */build.sh
	2. */build.sh downloads and compiles appropriate software
