apt-show-source - Lists source-packages.

       Dennis Schoen, dennis@debian.org

       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.

       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.
