Tool Command Language
     
         /tik*l/ (Tcl) An interpreted string processing
        language for issuing commands to {interactive} programs,
        developed by {John Ousterhout} at {UCB}.  Each {application
        program} can extend tcl with its own set of commands.
     
        Tcl is like a text-oriented {Lisp}, but lets you write
        algebraic expressions for simplicity and to avoid scaring
        people away.  Though originally designed to be a "scripting
        language" rather than for serious programming, Tcl has been
        used successfully for programs with hundreds of thousands of
        lines.
     
        It has a peculiar but simple {syntax}.  It may be used as an
        embedded {interpreter} in application programs.  It has
        {exceptions} and {packages} (called libraries), {name-spaces}
        for {procedures} and {variables}, and provide/require.  It
        supports {dynamic loading} of {object code}.  It is {eight-bit
        clean}.  It has only three variable types: strings, lists and
        {associative arrays} but no {structures}.
     
        Tcl and its associated {GUI} {toolkit}, {Tk} run on all
        flavors of {Unix}, {Microsoft Windows}, {Macintosh} and {VMS}.
        Tcl runs on the {Amiga} and many other {platforms}.
     
        Current version: 8.0.3, as of 1998-09-25.

        match on their output), {Cygnus Tcl Tools}, {[incr Tcl]} (adds
        classes and inheritence to Tcl), {Scriptics} (John
        Ousterhout's company that is the home of Tcl development and
        the TclPro tool suite), {Tcl Consortium} (a non-profit agency
        dedicated to promoting Tcl), {tclhttpd} (an embeddable
        Tcl-based web server), {tclx} (adds many commands to Tcl),
        {tcl-debug}.
