“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.”
