The book "Ubuntu 10.04 LTS Packaging Guide" is the part of the official documentation for Ubuntu 10.04 LTS.

The "Ubuntu 10.04 LTS Packaging Guide" is primarily addressed to those who would like to make and maintain Ubuntu packages. Although many of the concepts in this guide could be used to make binary packages for personal use, it is designed for those people wanting to distribute their packages to and for others. While it is also written with the Ubuntu Linux distribution in mind, it should also be useful for any Debian-based distribution.

There are several reasons you might want to learn how to package for Ubuntu. First, building and fixing Ubuntu packages is a great way to contribute to the Ubuntu community. It is also a good way to learn how Ubuntu and the applications you have installed work. Maybe you want to install a package that is not in the Ubuntu repositories. Hopefully after you have completed this guide you will have the tools and knowledge you need to do all of these things.
