<title>PackageKit</title>

    PackageKit lets applications query whether other packages are installed,

    regardless of the GNU/Linux distribution in which they are running.  If

    your application needs an extra package to be installed at runtime, it can

    ask PackageKit to download and install it.  For example, a multimedia

    application may need to download a codec, or an illustration program may

    need to download fonts as needed.

    Various GNOME applications use PackageKit in similar situations.  Totem,

    the media player, uses PackageKit to request installation of codecs when it

    tries to play a media file that it does not recognize.

    System-config-printer, a program to configure printers when they are

    plugged in, uses PackageKit to download and install printer drivers as needed.
