Extended Tcl (TclX) version 8.3.5 -- TclX runtime package
 Extended Tcl (TclX), is a set of extensions to Tcl, the Tool Command
 Language invented by Dr. John Ousterhout. Tcl is a powerful, yet simple
 embeddable programming language. Extended Tcl is oriented towards system
 programming tasks and large application development.
 .
 TclX provides additional interfaces to the operating system, and adds many
 new programming constructs, text manipulation tools, and debugging tools.
 .
 The tclx8.3 package doesn't include programs and libraries depending on Tk.
 You need the tkx8.3 package for these.
