-"""Services descriptor definitions.
-
-Contains message definitions and functions for converting
-service classes into transmittable message format.
-
-Describing an Enum instance, Enum class, Field class or Message class will
-generate an appropriate descriptor object that describes that class.
-This message can itself be used to transmit information to clients wishing
-to know the description of an enum value, enum, field or message without
-needing to download the source code.  This format is also compatible with
-other, non-Python languages.
-
-The descriptors are modeled to be binary compatible with:
-
-  http://code.google.com/p/protobuf/source/browse/trunk/src/google/protobuf/descriptor.proto
-
-NOTE: The names of types and fields are not always the same between these
-descriptors and the ones defined in descriptor.proto.  This was done in order
-to make source code files that use these descriptors easier to read.  For
-example, it is not necessary to prefix TYPE to all the values in
-FieldDescriptor.Variant as is done in descriptor.proto FieldDescriptorProto.Type.
-
-Example:
-
-  class Pixel(messages.Message):
-
-    x = messages.IntegerField(1, required=True)
-    y = messages.IntegerField(2, required=True)
-
-    color = messages.BytesField(3)
-
-  # Describe Pixel class using message descriptor.
-  fields = []
-
-  field = FieldDescriptor()
-  field.name = 'x'
-  field.number = 1
-  field.label = FieldDescriptor.Label.REQUIRED
-  field.variant = FieldDescriptor.Variant.INT64
-  fields.append(field)
-
-  field = FieldDescriptor()
-  field.name = 'y'
-  field.number = 2
-  field.label = FieldDescriptor.Label.REQUIRED
-  field.variant = FieldDescriptor.Variant.INT64
-  fields.append(field)
-
-  field = FieldDescriptor()
-  field.name = 'color'
-  field.number = 3
-  field.label = FieldDescriptor.Label.OPTIONAL
-  field.variant = FieldDescriptor.Variant.BYTES
-  fields.append(field)
-
-  message = MessageDescriptor()
-  message.name = 'Pixel'
-  message.fields = fields
-
-  # Describing is the equivalent of building the above message.
-  message == describe_message(Pixel)
-
-Public Classes:
-  EnumValueDescriptor: Describes Enum values.
-  EnumDescriptor: Describes Enum classes.
-  FieldDescriptor: Describes field instances.
-  FileDescriptor: Describes a single 'file' unit.
-  FileSet: Describes a collection of file descriptors.
-  MessageDescriptor: Describes Message classes.
-  MethodDescriptor: Describes a method of a service.
-  ServiceDescriptor: Describes a services.
-
-Public Functions:
-  describe_enum_value: Describe an individual enum-value.
-  describe_enum: Describe an Enum class.
-  describe_field: Describe a Field definition.
-  describe_file: Describe a 'file' unit from a Python module or object.
-  describe_file_set: Describe a file set from a list of modules or objects.
-  describe_message: Describe a Message definition.
-  describe_method: Describe a Method definition.
-  describe_service: Describe a Service definition.
