Gitano is an attempt at producing a strongly git-oriented workflow for hosting a number of git-based projects with complex rulesets. The focus is on ensuring that everything from the project code itself, to the setup of the Gitano instance to the rules which determine whether a pushed commit gets notified to an IRC channel via CIA.vc should all be in git.
All of Gitano's configuration is in git, a-la Gitosis or Gitolite. Any web services built on top are the purview of something else. Gitano allows the rulesets to define if anonymous access is allowed, meaning that the standard git server and a gitweb with appropriate check subs can be used without worry.
