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 Metakit database containing the VFS
onto the resulting executable.





To create the Metakit 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.

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.
