Welcome to the Apache Commons Wiki

Wiki MarkupWe're a \[http://wiki.apache.org/commons/FrontPage Commons\] community, dedicated to creating reusable library components in Java. Apache Commons is now using \[http://subversion.tigris.org/ Subversion\] as the version control systemCommons mainly uses Subversion as its version control system, however some components now use Git, and Commons components are available as read-only mirrors on Github.
