Perl is a very popular general-usage Unix programming language, famous for it's power and flexibility. It is used irreplaceably throughout the Internet, but also finds uses in bioinformatics, network and graphics programming, system administration, and finance applications. If you want to add a guestbook to your web site but cannot program in Perl, you should consider finding a place to download free Perl guestbook scripts.
Guestbooks allow visitors to your site to leave their name, contact information, and a comment if they want to. This is useful if you want like to see who and where your visitors are and get feedback from them. It's fairly simple to add a guestbook to your site, and in some cases you need only enter the script, while others offer an easy installation setup.
