3. TCLKIT
		Specify the path to a Tclkit that is runnable on the current
		system.  The default is "tclkit".  A working tclkit is required
		for cross-compiling Tclkits.

	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. 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.

	6. 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.

	7. 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

responsible for downloading the source code for the appropriate version that
will compile and link against the current version of Tcl (user requested
version can be found in "TCLVERS", while the actual version must be requested
from the "tclConfig.sh" script), compiling it, installing a functional copy
into the per-project "inst" directory, and installing anything that needs to
be in the Tclkit's VFS root into the per-project "out" directory.

The exception to this is the "kitsh" and "kitdll" projects.  They are the glue
that binds all the individual projects together into a single executable.  Its
build script does not create an "inst" or an "out" directory because it is not
a library.  Instead, it collects all the other project's "out" directories
into a single directory (starpack.vfs), as well a static file (boot.tcl).
It then compiles the source code, and then installs the VFS onto the resulting
executable.  The VFS is created by the "installvfs.tcl" script for Kitsh.  For
KitDLL the VFS is created by "dir2c.tcl".

If the "mk4tcl" project fails to build (or is not requested to be built),
the rest of the project will be built using zip files instead of Metakit
databases.

To create the storage database, one of two Tclkits is used (tried in this
order):
	1. The Tclkit specified by the TCLKIT environment variable (or
	   "tclkit" if that variable is not set) if it is functional; or
	2. The built Tclkit itself

The second method will not work if the built Tclkit is not executable on the
current platform (i.e., in the case of cross-compilation) and so it may be
necessary to bootstrap a runnable Tclkit first.

KitDLL mounts the VFS for every interpreter that calls Tcl_Init().  The system
VFS that is created at build time is mounted at /.KITDLL_TCL.  Additionally,
if there is a ZIP file appended to the DLL it will be mounted at /.KITDLL_USER
and if there is a ZIP file appended to the executable it will be mounted at
/.KITDLL_APP.  All VFSes that are mounted have the "lib" sub-directory appended
to the interpreters "auto_path" variable.
