This book will be an absolute necessity for CGI programmers writing in Perl. It's a description of a must-use tool by the tool's creator. It goes well beyond the online and POD documentation for CGI.pm. The example code snippets and programs are well chosen. There are a few problems: the organization of the reference section is confusing, and the descriptions of table(), Tr(), and td() don't explain how to enter attributes. (But the table examples show how to do that, so it's not much of a problem.) Summary: if you write CGI in Perl, get this book and use it.
