Medibuntu:
"Medibuntu is a packaging project dedicated to distributing software that cannot be included in Ubuntu for various reasons, related to geographical variations in legislation regarding intellectual property, security and other issues:

* patentability of software, algorithms, formats and other abstract creation
* legal restrictions on freedom of speech or communication
* restrictions on the use of certain types of technical solution, such as cryptography
* legal restrictions on imports of software technology, requiring for example specific permissions
* etc...

A lot of excellent free software and non-free software is affected by such restriction somewhere in the world, thus preventing its inclusion into Ubuntu that, for economy and simplicity, are generally identical for all countries.

We refuse to resign ourselves to abandoning software that may be legally useful somewhere, and we have chosen to provide it with "professional" quality packaging, easily usable within the context of Ubuntu.
This repository provides packages for Ubuntu distribution."

It is your legal responsibility to make sure that the software you are installing can be legally used in your country and for your intended purpose."
