Inside this book is material from the site interwoven with new topics such as a CPAN primer and a very basic look at using make. The thesis of the material is to provide some small examples of various system programming that are practical and within easy reach. A new programmer or someone just looking to expand their skillsets might find it useful. The book is licensed under the same Creative Commons license as the site. Note that since it was not professionally published (and at this time there is no compelling reason to do so) it has also not been professionally edited. Feel free to contact the author with corrections, suggestions or of course a brick.
