// This Gradle build file illustrates how to process Android
// applications.
// Usage:
//     gradle -b android.gradle proguard
//
// If you're using the Android SDK, the Ant release build and Eclipse export
// already take care of the proper settings. You only need to enable ProGuard
// by commenting in the corresponding line in project.properties. You can still
// add project-specific configuration in proguard-project.txt.
//
// This configuration file is for custom, stand-alone builds.

// Tell Gradle where to find the ProGuard task.
