.H 1 tksh

.I tksh

is an implementation of the Tcl C library

written on top of the library for the new KornShell

.RI ( ksh93 ).

.I tksh

emulates the behavior of Tcl by using the API that is provided for extending

.IR ksh93 ,

which is similar to the Tcl library in that it allows access to

variables, functions and other state of the interpreter.

This implementation requires no modification to

.IR ksh93 ,

and allows Tcl libraries such as Tk to run on top of

.I ksh93

unchanged,

making it possible to use shell scripts in

place of Tcl scripts.

.I ksh93

is well suited for use with Tk because it is

backward compatible with

.IR sh ,

making it both easy to learn and easy to extend

existing scripts to provide a graphical user interface.

.P

.I tksh

is not yet

another port of Tk to another language -- it allows Tcl scripts to run without

modification using the ksh93 internals.

This makes it possible to combine

Tcl and

.I ksh93 ,

which is useful for writing

.I ksh93

scripts that use components that have been implemented in Tcl

(such as Tk widgets).
