the only significant mode of use of the product.

### Cross-cutting architecture modules

There are some additional cross-cutting architecture modules that aren't themselves platforms:

#### Enterprise integration

Provides cross-cutting integration with Gradle's commercial product.

#### IDE integration

Provides cross-cutting integration with IDEs and other tooling.

#### Build infrastructure
