Query: [incr Tcl] from the Ground Up - highly recommended

I highly recommend this book. For the novice, this book provides material covering object oriented design, coding, debugging, and incr tcl. For the intermediate, this book discusses incr Tk , creating mega widgets, and the available incr widgets. For the expert, here is a reference manual for the latest incarnation of incr tcl. Lots of excellent material at a very reasonable price.
