Notes for whohas More information can be found at http://www.philippwesche.org/200811/whohas/intro.html Philipp L. Wesche whohas is a command line tool that allows querying several package lists at once - currently supported are Arch, Debian, Fedora, Gentoo, Mageia, Mandriva, openSUSE, Slackware, Source Mage, Ubuntu, FreeBSD, NetBSD, OpenBSD, Fink, MacPorts and Cygwin. whohas is written in Perl and was designed to help package maintainers find ebuilds, pkgbuilds and similar package definitions from other distributions to learn from.

I recommend using a terminal that recognises hyperlinks and allows easy forwarding to the browser.…
