Active: Webmin, Virtualmin GPL, Usermin<p>Patcher: Squid, various Drupal modules, Joomla and several modules, OpenACS and a few modules, Zope and a few modules, yum, SARG, a couple of CPAN modules, and at least as many more that I can't remember (a dozen years of Open Source involvement leads to a long list of project involvement, even though I don't write a lot of code, relatively speaking). A number of RPM spec files from various Linux distros.<p>One-off: Drupal, and too many others to name. Tons of RPM and deb packages; I maintain a couple dozen packages, so this happens every week or so.<p>Curious: nginx, mod_rails, RoR, Django, Catalyst, way too many to name.
