Absolutely everything on this page is released under GPL, and on a "It worked for me" basis. This site is mostly dedicated to providing up-to-date debs, that for some reason or another arent updated often in Debian sid, as well as providing an easy gateway for Debian users to access unofficial debs. However some items, especially in the misc section, may apply to linux in general. (NOTE: following mailto disabled (and not visible) for now, pending instructions for redirect.)
