#				  different TCL versions the version can be specified directly.
#				  If version is not specified (USE_TCL=yes) then the latest
#				  version is used (8.4 currently).
#				  Available values are: 84, 84-thread, 83, 82, 81 and 80.
# USE_TCL_BUILD	- Build time dependency on tcl. Same semantics as USE_TCL.
