 <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.
