+      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.
