Provides a package management service

 PackageKit allows performing simple software management tasks over a DBus
 interface e.g. refreshing the cache, updating, installing and removing
 software packages or searching for multimedia codecs and file handlers.
 .
 The work is done by backends which make use of the package manager shipped by
 the corresponding distribution. PackageKit is not meant to replace
 advanced tools like Synaptic.
 .
 The main benefits are:
  - unified interface on several distributions
  - fine grained privileges by using PolicyKit
  - independency from a running desktop session during the processing
