apt-show-source - Lists source-packages.
This program parses the APT lists for source packages and the dpkg status file and then lists every package with a higher version number than the one installed.
It may prove very useful if the "deb" entries in your APT sources.list point to stable and the "deb-src" entries point to unstable. With this program you are easily able to find out if there is a newer version of eg. Program XXXX in unstable.
Optional command line parameters are the DPKG Status file to use, the path to APT ’s list files and a package name. There are also options to display: all source-packages, verbose messages, version-only and command-line help.
