## Description

A GObject to use for accessing PackageKit asynchronously. If you're using PkClient to install, remove, or update packages, be prepared that the eula, gpg and trusted callbacks need to be rescheduled manually, as in http://www.packagekit.org/gtk-doc/introduction-ideas-transactions.html
