+openjdkjvmti plugin
+====
+
+This is a partial implementation of the JVMTI v1.2 interface for the android
+runtime as a plugin. This allows the use of agents that can modify the running
+state of the program by modifying dex files in memory and performing other
+operations on the global runtime state.
