apt-show-versions - Lists available package versions with distribution
apt-show-versions parses the dpkg status file and the APT lists for the
installed and available package versions and distribution and shows upgrade
options within the specific distribution of the selected package.
This is really useful if you have a mixed stable/testing environment and want to
list all packages which are from testing and can be upgraded in testing.
apt-show-versions uses caching for the status information of installed and
available packages. If you run apt-show-versions as root the cache is updated
