+// Options
+
+// Each of the definitions above may have "options" attached. These are
+// just annotations which may cause code to be generated slightly differently
+// or may contain hints for code that manipulates protocol messages.
+//
+// Clients may define custom options as extensions of the *Options messages.
+// These extensions may not yet be known at parsing time, so the parser cannot
+// store the values in them. Instead it stores them in a field in the *Options
+// message called uninterpreted_option. This field must have the same name
+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+// organization, or for experimental options, use field numbers 50000
+// through 99999. It is up to you to ensure that you do not use the
+// same number for multiple options.
+// * For options which will be published and used publicly by multiple
+// independent entities, e-mail protobuf-global-extension-registry@google.com
+// to reserve extension numbers. Simply provide your project name (e.g.
+// Object-C plugin) and your porject website (if available) -- there's no need
+// to explain how you intend to use them. Usually you only need one extension
+// number. You can declare multiple options with only one extension number by
+// putting them in a sub-message. See the Custom Options section of the docs
+// for examples:
+// https://developers.google.com/protocol-buffers/docs/proto#options
+// If this turns out to be popular, a web service will be set up

+ // the fields above, even though this is not technically guaranteed by the
+ // protobuf wire format. This theoretically could allow a plugin to stream
+ // in the FileDescriptorProtos and handle them one by one rather than read
+ // the entire set into memory at once. However, as of this writing, this

+ // This should be used to indicate errors in .proto files which prevent the
+ // code generator from generating correct code. Errors which indicate a
+ // problem in protoc itself -- such as the input CodeGeneratorRequest being
+ // unparseable -- should be reported by writing a message to stderr and

+ // The file name, relative to the output directory. The name must not
+ // contain "." or ".." components and must be relative, not be absolute (so,
+ // the file cannot lie outside the output directory). "/" must be used as
+ // the path separator, not "\".
+ //
+ // If the name is omitted, the content will be appended to the previous
+ // file. This allows the generator to break large files into small chunks,
+ // and allows the generated text to be streamed back to protoc so that large
+ // files need not reside completely in memory at one time. Note that as of
+ // this writing protoc does not optimize for this -- it will read the entire
+ // CodeGeneratorResponse before writing files to disk.
+ optional string name = 1;
+
+ // If non-empty, indicates that the named file should already exist, and the
+ // content here is to be inserted into that file at a defined insertion
+ // point. This feature allows a code generator to extend the output
+ // produced by another code generator. The original generator may provide
+ // 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.
+ optional string insertion_point = 2;
+
+ // The file contents.
