Detect and install additional Ubuntu driver packages

 This package aggregates and abstracts Ubuntu specific logic and knowledge
 about third-party driver packages. It provides:
 .
  - a Python API for detecting driver packages for a particular piece of
    hardware or the whole system.
 .
  - an "ubuntu-drivers" command line tool to list or install driver packages
    (mostly for integration in installers).
 .
  - some NVidia specific support code to find the most appropriate driver
    version, as well as setting up the alternatives symlinks that the
    proprietary NVidia and FGLRX packages use.
