python-packagekit 0.7.4-2ubuntu1 (i386 binary) in ubuntu quantal

 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.
 .
 This package provides Python bindings needed to write PackageKit backends
 in Python.
 If you want to use PackageKit in Python and don't write a backend, please
 use the GIRepository for PackageKit instead.
