Sometimes a packager asked himself, who has already packaged this Software? Maybe the Packagingfiles can help me to fix a error? Or maybe an other packager has a written a patch that i can use for my situation?
Philipp L. Wesche knows this situation, and he wrote a program, that allows to view in other Distributions and Repositories, who has a specific Software packaged. The commandline tool “whohas” supports Arch, Debian, Fedora, Gentoo, Mandriva, openSUSE, Slackware, linuxpackages.net, Source Mage, Ubuntu, FreeBSD, NetBSD, OpenBSD, Fink, MacPorts and Cygwin. Philipp wrote this tool in Perl and was designed to help package maintainers find ebuilds, pkgbuilds and similar package definitions to learn from.
