Tcl is a small programming language designed to be embedded into other programs to enable extensibility and customisation. Tk is an X window system toolkit providing graphic user interface facilities in connection with Tcl. Both were developed by John Ousterhout at the University of California at Berkeley, and are available free. Tcl and Tk together offer an easy route to graphic user interface programming in the X environment.This document is a practical introduction to using Tk and Tcl, concentrating on how they can be used to quickly develop flexible graphic user interface facilities. Some simple examples are worked through, and suggestions made as to how to proceed further.
