 // OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

-//  Based on original Protocol Buffers design by
-//  Sanjay Ghemawat, Jeff Dean, and others.
+//
+// Front-end for protoc code generator plugins written in C++.
+//
+// To implement a protoc plugin in C++, simply write an implementation of
+// CodeGenerator, then create a main() function like:
+//   int main(int argc, char* argv[]) {
+//     MyCodeGenerator generator;
+//     return google::protobuf::compiler::PluginMain(argc, argv, &generator);
+//   }
+// You must link your plugin against libprotobuf and libprotoc.
+//
+// To get protoc to use the plugin, do one of the following:
+// * Place the plugin binary somewhere in the PATH and give it the name
+//   "protoc-gen-NAME" (replacing "NAME" with the name of your plugin).  If you
+//   then invoke protoc with the parameter --NAME_out=OUT_DIR (again, replace
+//   "NAME" with your plugin's name), protoc will invoke your plugin to generate
+//   the output, which will be placed in OUT_DIR.
+// * Place the plugin binary anywhere, with any name, and pass the --plugin
+//   parameter to protoc to direct it to your plugin like so:
+//     protoc --plugin=protoc-gen-NAME=path/to/mybinary --NAME_out=OUT_DIR
+//   On Windows, make sure to include the .exe suffix:
+//     protoc --plugin=protoc-gen-NAME=path/to/mybinary.exe --NAME_out=OUT_DIR

+// Plugins written using C++ can use google/protobuf/compiler/plugin.h instead
+// of dealing with the raw protocol defined here.

+    // inserted text.  This is useful for languages like Python, where
+    // indentation matters.  In these languages, the insertion point comment
+    // should be indented the same amount as any inserted code will need to be
+    // in order to work correctly in that context.
+    //
+    // The code generator that generates the initial file and the one which
