"Teodor Zlatanov walks you through both the built-in Perl debugger and CPAN's Devel::ptkdb. The Perl debugger is powerful but frustrating to navigate. CPAN's Devel::ptkdb, on the other hand, works wonders by simplifying code debugging and thereby saving hours of your precious time. In his discussion Zlatanov concentrates on explaining debugging methods and general concepts rather than looking at specific tools."
"Bugs are as inevitable as death and taxes. Nevertheless, the following material should help you avoid the pitfalls of bugs. Some of the examples will require Perl 5.6.0 or at least 5.005. If you want to try the Emacs examples, you may also need to install the Emacs editor."
"I think debugging is so important that it should be allocated at least 30% of the project timeline. Extra debugging time will produce a better product. If, on the other hand, you cut debugging time to deliver the software more quickly, you will almost always double the amount of post-production time you spend fixing problems that come to light later."
