This is not a book, though the title sounds like one (or rather a whole shelf full of good books ;-). No, it's just another page at the Tcler's Wiki.
The ideas and contributions collected here needed some more indexing, and that's what this page tries to do. See also Where can I find a book about Tcl - Tcl articles.
