The tutorial is aimed at those who have some knowledge of programming, although you certainly don't have to be an expert. It is intended as a companion to the Tcl manual pages which provide a reference for all Tcl commands.

We hope that a professional programmer or MIT student can breeze through this book in one evening. By the end of the evening, that person should have learned Tcl, learned a little something about the Web, and not have been bored.
Tcl is a dynamic programming/scripting language based on concepts of Lisp, C, and Unix shells. It can be used interactively, or by running scripts which can use a package system for structuring. This book also discusses the GUI toolkit Tk.
