Tcl is a scripting language created by John Ousterhout. It can be used interactively, or by running scripts (programs) which can use a package system for structuring, hence allowing to do much with little code. This book discusses the GUI toolkit Tk in considerable extent, even though it's not in the title. For most users, Tcl/Tk form a single conceptual entity.
