What is DNX?
It is a modest script created to install a few free and non-free libraries and packages for Debian GNU/Linux based on the ubuntu-restricted-extras Ubuntu's package.
The main goal of this script is to have a one-step method to configure a Debian Workstation to decode mp3, avi, mpeg and work with flash, java and rar files.
DNX will add the contrib, non-free and Debian Multimedia repositories to your APT configuration file and install all the required packages.
To get a complete list of the packages that will be installed check here
