   apt-get - Cover for dpkg
   
   This is an allout cover for dpkg implementing a safer front end. It is
   based largely on libapt-pkg.

   The syntax is different, 
      apt-get [opt] command [things]
   Where command is:
      update - Resyncronize the package files from their sources
      upgrade - Smart-Download the newest versions of all packages
      dselect-upgrade - Follows dselect's changes to the Status: field
                       and installes new and removes old packages
      dist-upgrade - Powerful upgrader designed to handle the issues with
                    a new distribution.
      install - Download and install a given package (by name, not by .deb)
      check - Update the package cache and check for broken packages
      clean - Erase the .debs downloaded to /var/cache/apt/archives and
              the partial dir too
