Tcl/Tk 8.6.8

Tcl (Tool Command Language) is an interpreted scripting language optimized for portability and embedding. It's usually used in unison with its companion Tk GUI toolkit. All language operations are commands in prefix notation, and strings are used as most basic data construct, which both allow for variadic and dynamic uses. TclOO adds object-oriented semantics.
