Description: provides a software installation daemon
 PackageKit allows to perform 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 privilleges by using PolicyKit
 * independecy from a running desktop session during the processing
