For all of you who thought that the Expect man page was too long and too
terse at the same time, this book provides relief.  "Exploring Expect"
is an introduction and comprehensive tutorial to Expect.  Numerous
examples are provided and explained, demonstrating how to save you time
and money.  Example topics include how to write patterns, do signal
handling, use Expect as a telnetable daemon, and use Expect with Tk and
other Tcl extensions.

The book also includes an innovative introduction to Tcl - if you've
had trouble using Tcl before, all of a sudden, it will make a lot more
sense.  And while Exploring Expect concentrates primarily on using
Expect with Tcl, programmers attempting to automate interactive
programs using C, Perl, Python, or any other language will find this
book helpful because many of the concepts underlying Expect-like
programming are common to all languages.

Exploring Expect was originally based on Tcl 7.  But Don
wrote very carefully and it is not surprising that this book is still
accurate to Tcl - except in a couple places.  In particular, Tk's bind syntax is different now, so some of
the examples in the Expectk chapter aren't quite right anymore.
(But all the examples come with the Expect distribution and they've all
been kept up to date.)

Even if you're not interested in Expect, the book is a landmark
because it talks about a single extension and its domain in its
entirely,
covering everything you'd want to know about Tcl programming
including the pitfalls, without pulling any punches.
