NAME
       apt-show-source - Lists source-packages.
DESCRIPTION
       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.
COMMAND LINE PARAMETERS
       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.
