Source: apt-show-source Section: admin Priority: optional Maintainer: OHURA Makoto Standards-Version: 4.2.1 Build-Depends-Indep: perl Build-Depends: debhelper (>=9) Package: apt-show-source Architecture: all Depends: ${misc:Depends}, ${perl:Depends}, apt Description: Shows source-package information This program parses the APT lists for source packages and the dpkg status file and then lists every package with a different version number than the one installed. It's very useful if your deb-src sources.list entries point to unstable and your deb entries point to stable.
