<title>PackageKit</title>
<p>
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.
</p>
<p>
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.
