aptdaemon 0.45+bzr861-0ubuntu4 (amd64 binary) in ubuntu quantal

 Aptdaemon allows normal users to perform package management tasks, e.g.
 refreshing the cache, upgrading the system, installing or removing software
 packages.
 .
 Currently it comes with the following main features:
 .
  - Programming language independent D-Bus interface, which allows one to
    write clients in several languages
  - Runs only if required (D-Bus activation)
  - Fine grained privilege management using PolicyKit, e.g. allowing all
    desktop user to query for updates without entering a password
  - Support for media changes during installation from DVD/CDROM
  - Support for debconf (Debian's package configuration system)
  - Support for attaching a terminal to the underlying dpkg call
 .
 This package contains the aptd script and all the data files required to run
 the daemon. Moreover it contains the aptdcon script, which is a command
 line client for aptdaemon. The API is not stable yet.
