Xircles is the management platform deployed at The Codehaus to help provide a consistent and manageable environment for opensource development. Through Xircles, projects can manage almost every aspect of their environment.
Xircles is closed source software produced by OpenXource for the purposes of managing multi-project opensource development sites. OpenXource provides The Codehaus with this software to help manage the environment. Unsurprisingly, the founders of OpenXource are the despots (Ben Walding, Bob 'The Despot' McWhirter) at The Codehaus.
The Codehaus Xircles instance can be found at https://xircles.codehaus.org; you use your Codehaus LDAP credentials to login to this application.
