          Gradle is a build system which offers you ease, power and freedom.
          You can choose the balance for yourself. It has powerful multi-project
          build support. It has a layer on top of Ivy that provides a
          build-by-convention integration for Ivy. It gives you always the choice
          between the flexibility of Ant and the convenience of a
          build-by-convention behavior.
