Plain Old Documentation (POD)
Writing a utility is one thing. Getting people to use it is another. In order for a program to become popular, people have to know how to use the thing.
All the Perl scripts in this book have a POD section. However, because the book also documents the scripts, the documentation has been omitted in the print version of the scripts. The downloadable version of the scripts do have a POD section in them.
