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.
 .
 Its main benefits are:
  - Unified developer and user interface on many distributions
  - Fine-grained permission control via PolicyKit
  - On-demand installation of missing system components
