Deb-o-Matic

Deb-o-Matic is an easy to use utility to build Debian source packages, meant
to help developers to automate the building of their packages with a tool that
requires limited user interaction and a simple startup configuration.

It provides some useful features such as automatic chroot update, rebuilds of
source packages, post-build checks, and much more. It is also extendable using
modules that are loaded and executed during the build phases.
