+Description:
+Android protobuf library contains the nano version of the Java protobuf library,
+which generates Java-files with fewer methods than the protobuf lite compiler,
+which is needed for big Java projects since Android has a maximum number of
+methods per application.
+
+The 'android_protoc' target file list is taken from COMPILER_SRC_FILES in
+src/Android.mk.
+
+See //third_party/protobuf for the C++ version of protobuf.
+
+Local Modifications:
+None.
