Ubuntu add repostiories or PPA's to system using deb package.

Provide a relatively (doesn't have to be a gui) easy way to add Ubuntu repositories or PPA's to a deb file that will be hosted in its own PPA library or repository for others to add to their system that will add any and all repositories or ppa's to their system that was provided by the deb file that we create and host in our ppa or repository. A working example can be found at [login to view URL] they have a package there that users can download which adds their repository to the users system. This is what I'm looking for as well, however I want to host the deb file in a ppa that when used will add all the repositories or ppa's that i've set in the deb file.
