If you are like me, you probably have many examples of web forms that you find yourself filling out over and over again. Sean's done a great job of showing how this powerful library can be used to make tools that automate various tasks on the Web. This book tells you how you can write your own useful web client applications with LWP and its related HTML modules.
And the good news is that LWP can help automate them all. These days there is almost no end to the information at our fingertips: news, stock quotes, weather, government info, shopping, discussion groups, product info, reviews, games, and other entertainment. A lot has happened to the web since then. As a result, I got involved in LWP, the Perl web client library. Over time, I moved from hacking on the server side to the client side but stayed with Perl as the programming language of choice. CGI was not invented yet, so all we had were servlets (although we didn't call them that then). What was different was it was implemented in Perl. The first versions of Mosaic had just showed up, Gopher and Wais were still hot technology, and I discovered an HTTP server program called Plexus.
