Since no one writes perfect code all the time, the debugger is explained with its various options. Packages, modules and objects are discussed in chapters 7 and 8. A short explanation and an example give you a good idea of how each standard module, delivered with Perl, is used. CGI is covered in chapters 9 through 11. I feel this section will be used the most, because CGI together with the Internet is such a hot item.
Many web pages make use of CGI scripts.
This module will reduce the forking of extra processes each time a script is executed. Installing this module and making use of its capabilities can speed up execution on the server. Chapter 12 explains the connection between databases and Perl. Databases are also a hot item on the Internet these days. Each chapter starts with a short description of the service, followed by the key words in alphabetical order along with their uses.
