It's not technically an openSUSE Tool, but openSUSE's infrastructure relies on it - so subproject.

GoCD is used in software development to help teams and organizations automate the continuous delivery (CD) of software.

It supports automating the entire build-test-release process from code check-in to deployment.

It helps to keep producing valuable software in short cycles and ensure that the software can be reliably released at any time.

It supports several version control tools including Git, Mercurial, Subversion, Perforce and Team Foundation Server.
Other version control software can be supported by installing additional plugins.
