+//
+// raw source files --(metalava)--> stub source files --(javac)--> stub jar files
+//
+// The metalava conversion is done by droidstub modules *-api-stubs-docs.
+// The javac compilation is done by java_library modules android_*_stubs_current.
+// The metalava conversion is also responsible for creating API signature files
+// and comparing them against the last API signature in api/*-current.txt files
+// and also against the latest frozen API signature in prebuilts/sdk/*/*/api/android.txt
+// files.
