      2 // This Gradle build file illustrates how to process ProGuard
      3 // (including its main application, its GUI, its Ant task, and its WTK plugin),
      4 // and the ReTrace tool, all in one go.
      5 // Configuration files for typical applications will be very similar.
      6 // Usage:
      7 //     gradle -b proguardall.gradle proguard
      8 //
      9 
     10 // Tell Gradle where to find the ProGuard task.
