This package is a disgrace for O'Reilly. Large
portions of the software on the CD are not
functional (even after applying Service Pack 1).
For example, neither the Visual Package Manager
VPM nor Perl/Tk work. Even the Perl/Tk demo
program on the CD does not work, which speaks
volumes for quality control. At least standalone
perl and the debugger run, but if you had
planned (like me) to use Perl with Tk to build
user interfaces - forget it. I essentially blew
$150.- for a set of manuals, without working
software.
