What is Continuum?

Continuum is the tool used to monitor changes in Subversion (commits) and schedule frequent re-builds, based on those changes. Continuum exploits project information stored in the POM, and uses Maven to perform the builds.
Continuum understands the projects dependencies and builds projects in the proper order.

The repeatability element of project building is guaranteed by the fact that the tooling and configuration used on the developer's workstation or the build workstation is exactly the same.
