You'll want to use the insertion points that are emitted by the code
generators in the core implementation. There are some references to these in
plugin.proto, but I'm not sure that we have a document listing all the
available insertion points. I believe that these insertion points are
available
Is there a simpler way of creating a plugin to rewrite parts of the
generated code from the default implementation? So if I want to
generate the java/c++/python code for a service, but I basically want
all the surroundings, and just modify some of the body of the
class(es), is there any easy way
