I wrote this book to fill in the gap between those Perl books which were too advanced and those Perl books which were too elementary. This is the perfect book for you if you are new to Perl. The style of the book is to explain concepts by giving simple details and by following these details with clear and complete Perl programs. So that the book would also have appeal for all Perl programmers, there are also many advanced topics in the book which are generally not covered in an introductory text. These include Web Programming (CGI), Database Programming (DBI) and Graphical User Interface Programming (using Tk).
