4. STATICTK
		Specify this as "1" to statically link to Tk.  The default
		action on most platforms is to dynamically link to Tk.  When
		building KitDLL, STATICTK is "1" by default.  If you want to
		enable dynamic linking of Tk with KitDLL you will have to
		specify this as "-1".

	5. STATICMK4
		Specify this as "0" to attempt to create create the "mk4tcl"
		project as a shared object.  If this fails, it will fall back
		to building statically.  Specify it as "-1" to force building
		it as a shared object.  Any other value, including being unset
		results in "mk4tcl" being built and linked statically.  KitDILL
		sets this to variable to "0".  If Metakit4 is built shared, it
		cannot be used for the kit storage for Tclkit.

	6. STRIP
		Specifies the tool you wish to be called to strip object files,
		archives, and shared objects.  The default is "strip".  You
		should probably set this if you are cross-compiling.

	7. KITCREATOR_PKGS
		Specify which non-required packages to build.  The default list
		is:
			tk itcl mk4tcl

		If mk4tcl is not present a Zip-based storage mechanism will be
		used instead.  To specify that the default be used, do not set
		this or set it to the empty string.  To specify that no
		non-required packages be built, set it to a string that
		contains only white space.

		If "kitdll" is specified in the list the target becomes KitDLL
		and no Tclkit will built, but instead libtclkit.

	8. KITCREATOR_MINENCODINGS
		Set this variable to a non-empty string to generate a Tclkit
		without all encodings, only including the following:
			ascii.enc cp1252.enc iso8859-1.enc iso8859-15.enc
			iso8859-2.enc koi8-r.enc macRoman.enc

	9. KITCREATOR_MINBUILD
		Set this variable to a non-empty string to exclude unnecessary
		packages from Tcl build.  This excludes the following packages:
			tcltest

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.

Method of Operation

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