If it was possible to give this book 0 stars I certainly would have. As others have said before, this is just a bad book.

I usually find O'Reilly books excellent but this one is a disppointment. You could print out the Tcl manual pages and get as much information. Examples are few and meager. There should at least be a brief primer, with examples, to get the reader accustomed to the Tcl way of doing things. There's a tips and hints chapter at the end that's good, but it's all too short.

The previous reviewers seemed to think that this book would teach them the way of TCL/TK and were thoroughly disappointed. But what they failed to realize that this book is meant to be nothing more then a reference book. Perhaps if they had paid attention to the product description, they would have been prepared.

A thing to keep in mind, anytime an O'Reilly book has "...in a Nutshell" after the title... it's a reference book. Pure and simple. Say it with me, people. R-E-F-E-R-E-N-C-E. Not to be confused with "Master TCL/TK in 24 hours" or what have you.

So, keeping that in mind, as a reference book, it does a fantastic job as the rest have stated. Makes for a good "dictionary" so to speak.
