setup-packaging-environment aims to make it more straightforward for new contributors to get their Ubuntu
installation ready for packaging work. It ensures that all four components from Ubuntu's official
repositories are enabled along with their corresponding source repositories. It also installs a minimal
set of packages needed for Ubuntu packaging work (ubuntu-dev-tools, devscripts, debhelper, patchutils,
pbuilder, and build-essential). Finally, it assists in defining the DEBEMAIL and DEBFULLNAME environment
variables.
