Novo Builder is a Debian GNU/Linux tool for creating your own up-to-date Ubuntu variants customized to include the programs, themes, and customized settings that you want. It provides a convenient interface for editing and building your very own OS in under one hour (depending on your Internet speeds). Novo is so simple that a general Linux user will produce results on their very first try, but it's also powerful enough that advanced hackers are able to make it preform tasks in the way they want with full control of the end results. One of the best features of Novo is how simple it is to share what you create, so others can use your ideas in their own projects. Novo can store any number of projects, so you can have a large collection of pre-sets that you can run. Novo is able to build an OS for i386 and amd64 (if your host uses the amd64 architecture) and is able to customize which repositories you use to build and which packages you include.
