Perl is a well-known scripting language that is employed to make different web-oriented applications, which includes CGI scripts. One of the attributes which distinguish it from alternative languages is the employment of modules - batches of Perl code that perform predefined tasks and they're commonly accepted. In simple terms, rather than generating tailor-made program code to make something or pasting tens and hundreds of lines of program code inside your script, you can "call" some module that already exists for this particular process and use just several lines of program code. Consequently, your script shall be executed a lot faster because it is much smaller. Using modules will, in addition make your script much easier to edit due to the fact that you'll need to search through a smaller amount of program code. If you want to use Perl on your site, you have to ensure that the necessary modules can be found on your server.
