// This Gradle build file illustrates how to process Android
// applications.
//
// If you're using the Android SDK, the provided build systems with Gradle,
// Android Studio, Eclipse, and Ant already take care of the proper settings.
// You only need to enable ProGuard as explained in the Android documentation.
// You can still add project-specific configuration in proguard-project.txt.
//
// This configuration file is for custom, stand-alone builds.
// Usage:
//     gradle -b android.gradle proguard

// Tell Gradle where to find the ProGuard task.
