The book comes with a CD-ROM that has all the examples in the book, plus a variety of Tcl/Tk freeware from the net. The first printing has Tcl/Tk 8.0a2 releases on it. In addition, due to my own mis-intpretation of the ISO-9660 spec, the CD-ROM is not readable on some systems. I'll fix the CD-ROM for the 2nd printing of the book, which will appear sometime in the fall of 1997. You can tell the print run by looking for a sequence of numbers on the first page. The numbers count down from 10 and end when the print number. The second printing will end with 2:
10 9 8 7 6 5 4 3 2
