+ // insertion points by placing special annotations in the file that look
+ // like:
+ // @@protoc_insertion_point(NAME)
+ // The annotation can have arbitrary text before and after it on the line,
+ // which allows it to be placed in a comment. NAME should be replaced with
+ // an identifier naming the point -- this is what other generators will use
+ // as the insertion_point. Code inserted at this point will be placed
+ // immediately above the line containing the insertion point (thus multiple
+ // insertions to the same point will come out in the order they were added).
+ // The double-@ is intended to make it unlikely that the generated code
+ // could contain things that look like insertion points by accident.
+ //
+ // For example, the C++ code generator places the following line in the
+ // .pb.h files that it generates:
+ // // @@protoc_insertion_point(namespace_scope)
+ // This line appears within the scope of the file's package namespace, but
+ // outside of any particular class. Another plugin can then specify the
+ // insertion_point "namespace_scope" to generate additional classes or
+ // other declarations that should be placed in this scope.
+ //
+ // Note that if the line containing the insertion point begins with
+ // whitespace, the same whitespace will be added to every line of the
+ // 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
+ // inserts into it must both run as part of a single invocation of protoc.
+ // Code generators are executed in the order in which they appear on the
+ // command line.
+ //
+ // If |insertion_point| is present, |name| must also be present.
