+protobufjs/ext/descriptor
+=========================
+
+Experimental extension for interoperability with [descriptor.proto](https://github.com/google/protobuf/blob/master/src/google/protobuf/descriptor.proto) types.
+
+Usage
+-----
+
+```js
+var protobuf   = require("protobufjs"), // requires the full library
+    descriptor = require("protobufjs/ext/descriptor");
+
+var root = ...;
+
+// convert any existing root instance to the corresponding descriptor type
+var descriptorMsg = root.toDescriptor("proto2");
+// ^ returns a FileDescriptorSet message, see table below
+
+// encode to a descriptor buffer
+var buffer = descriptor.FileDescriptorSet.encode(descriptorMsg).finish();
+
+// decode from a descriptor buffer
+var decodedDescriptor = descriptor.FileDescriptorSet.decode(buffer);
+
+// convert any existing descriptor to a root instance
+root = protobuf.Root.fromDescriptor(decodedDescriptor);
+// ^ expects a FileDescriptorSet message or buffer, see table below
+
+// and start all over again
+```
+
+API
+---
+
+The extension adds `.fromDescriptor(descriptor[, syntax])` and `#toDescriptor([syntax])` methods to reflection objects and exports the `.google.protobuf` namespace of the internally used `Root` instance containing the following types present in descriptor.proto:
+
+| Descriptor type               | protobuf.js type | Remarks
+|-------------------------------|------------------|---------
+| **FileDescriptorSet**         | Root             |
+| FileDescriptorProto           |                  | dependencies are not supported
+| FileOptions                   |                  |
+| FileOptionsOptimizeMode       |                  |
+| SourceCodeInfo                |                  | not supported
+| SourceCodeInfoLocation        |                  |
+| GeneratedCodeInfo             |                  | not supported
+| GeneratedCodeInfoAnnotation   |                  |
+| **DescriptorProto**           | Type             |
+| MessageOptions                |                  |
+| DescriptorProtoExtensionRange |                  |
+| DescriptorProtoReservedRange  |                  |
+| **FieldDescriptorProto**      | Field            |
+| FieldDescriptorProtoLabel     |                  |
+| FieldDescriptorProtoType      |                  |
+| FieldOptions                  |                  |
+| FieldOptionsCType             |                  |
+| FieldOptionsJSType            |                  |
+| **OneofDescriptorProto**      | OneOf            |
+| OneofOptions                  |                  |
+| **EnumDescriptorProto**       | Enum             |
+| EnumOptions                   |                  |
+| EnumValueDescriptorProto      |                  |
+| EnumValueOptions              |                  | not supported
+| **ServiceDescriptorProto**    | Service          |
+| ServiceOptions                |                  |
+| **MethodDescriptorProto**     | Method           |
+| MethodOptions                 |                  |
+| UninterpretedOption           |                  | not supported
+| UninterpretedOptionNamePart   |                  |
+
+Note that not all features of descriptor.proto translate perfectly to a protobuf.js root instance. A root instance has only limited knowlege of packages or individual files for example, which is then compensated by guessing and generating fictional file names.
+
+When using TypeScript, the respective interface types can be used to reference specific message instances (i.e. `protobuf.Message<IDescriptorProto>`).
