== Declaring the dependencies substituted by an included build

By default, Gradle will configure each included build in order to determine the dependencies it can provide. The algorithm for doing this is very simple: Gradle will inspect the `group` and `name` for the projects in the included build, and substitute project dependencies for any matching external dependency.
