-Equal returns true iff protocol buffers a and b are equal.
-The arguments must both be pointers to protocol buffer structs.

-Equality is defined in this way:
-  - Two messages are equal iff they are the same type,
-    corresponding fields are equal, unknown field sets
-    are equal, and extensions sets are equal.
-  - Two set scalar fields are equal iff their values are equal.
-    If the fields are of a floating-point type, remember that
-    NaN != x for all x, including NaN. If the message is defined
-    in a proto3 .proto file, fields are not "set"; specifically,
-    zero length proto3 "bytes" fields are equal (nil == {}).
-  - Two repeated fields are equal iff their lengths are the same,
-    and their corresponding elements are equal. Note a "bytes" field,
-    although represented by []byte, is not a repeated field and the
-    rule for the scalar fields described above applies.
-  - Two unset fields are equal.
-  - Two unknown field sets are equal if their current
-    encoded state is equal.
-  - Two extension sets are equal iff they have corresponding
-    elements that are pairwise equal.
-  - Two map fields are equal iff their lengths are the same,
-    and they contain the same set of elements. Zero-length map
-    fields are equal.
-  - Every other combination of things are not equal.

-Package proto converts data structures to and from the wire format of
-protocol buffers.  It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
-  - Names are turned from camel_case to CamelCase for export.
-  - There are no methods on v to set fields; just treat
-	them as structure fields.
-  - There are getters that return a field's value if set,
-	and return the field's default value if unset.
-	The getters work even if the receiver is a nil message.
-  - The zero value for a struct is its correct initialization state.
-	All desired fields must be set before marshaling.
-  - A Reset() method will restore a protobuf struct to its zero state.
-  - Non-repeated fields are pointers to the values; nil means unset.
-	That is, optional or required field int32 f becomes F *int32.
-  - Repeated fields are slices.
-  - Helper functions are available to aid the setting of fields.
-	msg.Foo = proto.String("hello") // set field
-  - Constants are defined to hold the default values of all fields that
-	have them.  They have the form Default_StructName_FieldName.
-	Because the getter methods handle defaulted values,
-	direct use of these constants should be rare.
-  - Enums are given type names and maps from names to values.
-	Enum values are prefixed by the enclosing message's name, or by the
-	enum's type name if it is a top-level enum. Enum types have a String
-	method, and a Enum method to assist in message construction.
-  - Nested messages, groups and enums have type names prefixed with the name of
-	the surrounding message type.
-  - Extensions are given descriptor names that start with E_,
-	followed by an underscore-delimited list of the nested messages
-	that contain it (if any) followed by the CamelCased name of the
-	extension field itself.  HasExtension, ClearExtension, GetExtension
-	and SetExtension are functions for manipulating extensions.
-  - Oneof field sets are given a single field in their message,
-	with distinguished wrapper types for each possible field value.
-  - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
-  - Non-repeated fields of non-message type are values instead of pointers.
-  - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
-	package example;
-
-	enum FOO { X = 17; }
-
-	message Test {
-	  required string label = 1;
-	  optional int32 type = 2 [default=77];
-	  repeated int64 reps = 3;
-	  optional group OptionalGroup = 4 {
-	    required string RequiredField = 5;
-	  }
-	  oneof union {
-	    int32 number = 6;
-	    string name = 7;

-// `Any` contains an arbitrary serialized protocol buffer message along with a
-// URL that describes the type of the serialized message.
-//
-// Protobuf library provides support to pack/unpack Any values in the form
-// of utility functions or additional generated methods of the Any type.
-//
-// Example 1: Pack and unpack a message in C++.
-//
-//     Foo foo = ...;
-//     Any any;
-//     any.PackFrom(foo);
-//     ...
-//     if (any.UnpackTo(&foo)) {
-//       ...
-//     }
-//
-// Example 2: Pack and unpack a message in Java.
-//
-//     Foo foo = ...;
-//     Any any = Any.pack(foo);
-//     ...
-//     if (any.is(Foo.class)) {
-//       foo = any.unpack(Foo.class);
-//     }
-//
-//  Example 3: Pack and unpack a message in Python.
-//
-//     foo = Foo(...)
-//     any = Any()
-//     any.Pack(foo)
-//     ...
-//     if any.Is(Foo.DESCRIPTOR):
-//       any.Unpack(foo)
-//       ...
-//
-//  Example 4: Pack and unpack a message in Go
-//
-//      foo := &pb.Foo{...}
-//      any, err := ptypes.MarshalAny(foo)
-//      ...
-//      foo := &pb.Foo{}
-//      if err := ptypes.UnmarshalAny(any, foo); err != nil {
-//        ...
-//      }
-//
-// The pack methods provided by protobuf library will by default use
-// 'type.googleapis.com/full.type.name' as the type URL and the unpack
-// methods only use the fully qualified type name after the last '/'
-// in the type URL, for example "foo.bar.com/x/y.z" will yield type
-// name "y.z".
-//
-//
-// JSON
-// ====
-// The JSON representation of an `Any` value uses the regular
-// representation of the deserialized, embedded message, with an
-// additional field `@type` which contains the type URL. Example:
-//
-//     package google.profile;
-//     message Person {
-//       string first_name = 1;
-//       string last_name = 2;
-//     }
-//
-//     {
-//       "@type": "type.googleapis.com/google.profile.Person",
-//       "firstName": <string>,
-//       "lastName": <string>
-//     }
-//
-// If the embedded message type is well-known and has a custom JSON
-// representation, that representation will be embedded adding a field
-// `value` which holds the custom JSON in addition to the `@type`
-// field. Example (for message [google.protobuf.Duration][]):
-//
-//     {
-//       "@type": "type.googleapis.com/google.protobuf.Duration",
-//       "value": "1.212s"
-//     }
-//
-type Any struct {
-	// A URL/resource name that uniquely identifies the type of the serialized
-	// protocol buffer message. The last segment of the URL's path must represent
-	// the fully qualified name of the type (as in
-	// `path/google.protobuf.Duration`). The name should be in a canonical form
-	// (e.g., leading "." is not accepted).
-	//
-	// In practice, teams usually precompile into the binary all types that they
-	// expect it to use in the context of Any. However, for URLs which use the
-	// scheme `http`, `https`, or no scheme, one can optionally set up a type
-	// server that maps type URLs to message definitions as follows:
-	//
-	// * If no scheme is provided, `https` is assumed.
-	// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
-	//   value in binary format, or produce an error.
-	// * Applications are allowed to cache lookup results based on the
-	//   URL, or have them precompiled into a binary to avoid any
-	//   lookup. Therefore, binary compatibility needs to be preserved
-	//   on changes to types. (Use versioned type names to manage
-	//   breaking changes.)
-	//
-	// Note: this functionality is not currently available in the official
-	// protobuf release, and it is not used for type URLs beginning with
-	// type.googleapis.com.
-	//
-	// Schemes other than `http`, `https` (or the empty scheme) might be
-	// used with implementation specific semantics.

-// `Any` contains an arbitrary serialized protocol buffer message along with a
-// URL that describes the type of the serialized message.
-//
-// Protobuf library provides support to pack/unpack Any values in the form
-// of utility functions or additional generated methods of the Any type.
-//
-// Example 1: Pack and unpack a message in C++.
-//
-//     Foo foo = ...;
-//     Any any;
-//     any.PackFrom(foo);
-//     ...
-//     if (any.UnpackTo(&foo)) {
-//       ...
-//     }
-//
-// Example 2: Pack and unpack a message in Java.
-//
-//     Foo foo = ...;
-//     Any any = Any.pack(foo);
-//     ...
-//     if (any.is(Foo.class)) {
-//       foo = any.unpack(Foo.class);
-//     }
-//
-//  Example 3: Pack and unpack a message in Python.
-//
-//     foo = Foo(...)
-//     any = Any()
-//     any.Pack(foo)
-//     ...
-//     if any.Is(Foo.DESCRIPTOR):
-//       any.Unpack(foo)
-//       ...
-//
-//  Example 4: Pack and unpack a message in Go
-//
-//      foo := &pb.Foo{...}
-//      any, err := ptypes.MarshalAny(foo)
-//      ...
-//      foo := &pb.Foo{}
-//      if err := ptypes.UnmarshalAny(any, foo); err != nil {
-//        ...
-//      }
-//
-// The pack methods provided by protobuf library will by default use
-// 'type.googleapis.com/full.type.name' as the type URL and the unpack
-// methods only use the fully qualified type name after the last '/'
-// in the type URL, for example "foo.bar.com/x/y.z" will yield type
-// name "y.z".
-//
-//
-// JSON
-// ====
-// The JSON representation of an `Any` value uses the regular
-// representation of the deserialized, embedded message, with an
-// additional field `@type` which contains the type URL. Example:
-//
-//     package google.profile;
-//     message Person {
-//       string first_name = 1;
-//       string last_name = 2;
-//     }
-//
-//     {
-//       "@type": "type.googleapis.com/google.profile.Person",
-//       "firstName": <string>,
-//       "lastName": <string>
-//     }
-//
-// If the embedded message type is well-known and has a custom JSON
-// representation, that representation will be embedded adding a field
-// `value` which holds the custom JSON in addition to the `@type`
-// field. Example (for message [google.protobuf.Duration][]):
-//
-//     {
-//       "@type": "type.googleapis.com/google.protobuf.Duration",
-//       "value": "1.212s"
-//     }
-//
-message Any {
-  // A URL/resource name that uniquely identifies the type of the serialized
-  // protocol buffer message. The last segment of the URL's path must represent
-  // the fully qualified name of the type (as in
-  // `path/google.protobuf.Duration`). The name should be in a canonical form
-  // (e.g., leading "." is not accepted).
-  //
-  // In practice, teams usually precompile into the binary all types that they
-  // expect it to use in the context of Any. However, for URLs which use the
-  // scheme `http`, `https`, or no scheme, one can optionally set up a type
-  // server that maps type URLs to message definitions as follows:
-  //
-  // * If no scheme is provided, `https` is assumed.
-  // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
-  //   value in binary format, or produce an error.
-  // * Applications are allowed to cache lookup results based on the
-  //   URL, or have them precompiled into a binary to avoid any
-  //   lookup. Therefore, binary compatibility needs to be preserved
-  //   on changes to types. (Use versioned type names to manage
-  //   breaking changes.)
-  //
-  // Note: this functionality is not currently available in the official
-  // protobuf release, and it is not used for type URLs beginning with
-  // type.googleapis.com.
-  //
-  // Schemes other than `http`, `https` (or the empty scheme) might be
-  // used with implementation specific semantics.
-  //
-  string type_url = 1;
-
-  // Must be a valid serialized protocol buffer of the above specified type.
-  bytes value = 2;

-// A Duration represents a signed, fixed-length span of time represented
-// as a count of seconds and fractions of seconds at nanosecond
-// resolution. It is independent of any calendar and concepts like "day"
-// or "month". It is related to Timestamp in that the difference between
-// two Timestamp values is a Duration and it can be added or subtracted
-// from a Timestamp. Range is approximately +-10,000 years.
-//
-// # Examples
-//
-// Example 1: Compute Duration from two Timestamps in pseudo code.
-//
-//     Timestamp start = ...;
-//     Timestamp end = ...;
-//     Duration duration = ...;
-//
-//     duration.seconds = end.seconds - start.seconds;
-//     duration.nanos = end.nanos - start.nanos;

-//     } else if (durations.seconds > 0 && duration.nanos < 0) {
-//       duration.seconds -= 1;
-//       duration.nanos += 1000000000;
-//     }
-//
-// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
-//
-//     Timestamp start = ...;
-//     Duration duration = ...;
-//     Timestamp end = ...;
-//
-//     end.seconds = start.seconds + duration.seconds;
-//     end.nanos = start.nanos + duration.nanos;
-//
-//     if (end.nanos < 0) {
-//       end.seconds -= 1;
-//       end.nanos += 1000000000;
-//     } else if (end.nanos >= 1000000000) {
-//       end.seconds += 1;
-//       end.nanos -= 1000000000;
-//     }
-//
-// Example 3: Compute Duration from datetime.timedelta in Python.
-//
-//     td = datetime.timedelta(days=3, minutes=10)
-//     duration = Duration()
-//     duration.FromTimedelta(td)

-// seconds long, i.e. leap seconds are "smeared" so that no leap second
-// table is needed for interpretation. Range is from
-// 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z.
-// By restricting to that range, we ensure that we can convert to

-// # Examples
-//
-// Example 1: Compute Timestamp from POSIX `time()`.
-//
-//     Timestamp timestamp;
-//     timestamp.set_seconds(time(NULL));
-//     timestamp.set_nanos(0);

-//
-// # JSON Mapping
-//
-// In JSON format, the Timestamp type is encoded as a string in the
-// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
-// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
-// where {year} is always expressed using four digits while {month}, {day},
-// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
-// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
-// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
-// is required. A proto3 JSON serializer should always use UTC (as indicated by
-// "Z") when printing the Timestamp type and a proto3 JSON parser should be
-// able to accept both UTC and other timezones (as indicated by an offset).
-//
-// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
-// 01:30 UTC on January 15, 2017.
-//
-// In JavaScript, one can convert a Date object to this format using the
-// standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString]
-// method. In Python, a standard `datetime.datetime` object can be converted
-// to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime)
-// with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one
-// can use the Joda Time's [`ISODateTimeFormat.dateTime()`](
-// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime--

+[![Build Status](https://travis-ci.org/nxadm/tail.svg?branch=master)](https://travis-ci.org/nxadm/tail)
+
+This is repo is forked from the dormant upstream repo at
+[hpcloud](https://github.com/hpcloud/tail). This fork adds support for go
+modules, updates the dependencies, adds features and fixes bugs. Go 1.9 is
+the oldest compiler release supported.
+
+# Go package for tail-ing files
+
+A Go package striving to emulate the features of the BSD `tail` program.
+
+```Go
+t, err := tail.TailFile("/var/log/nginx.log", tail.Config{Follow: true})
+if err != nil {
+    panic(err)
+}
+
+for line := range t.Lines {
+    fmt.Println(line.Text)
+}
+```
+
+See [API documentation](http://godoc.org/github.com/nxadm/tail).
+
+## Log rotation
+
+Tail comes with full support for truncation/move detection as it is
+designed to work with log rotation tools.
+
+## Installing
+
+    go get github.com/nxadm/tail/...
+
+## Windows support
+
+This package [needs assistance](https://github.com/nxadm/tail/labels/Windows) for full Windows support.

-- Structure your BDD-style tests expressively:
-    - Nestable [`Describe`, `Context` and `When` container blocks](http://onsi.github.io/ginkgo/#organizing-specs-with-containers-describe-and-context)
-    - [`BeforeEach` and `AfterEach` blocks](http://onsi.github.io/ginkgo/#extracting-common-setup-beforeeach) for setup and teardown
-    - [`It` and `Specify` blocks](http://onsi.github.io/ginkgo/#individual-specs-) that hold your assertions
-    - [`JustBeforeEach` blocks](http://onsi.github.io/ginkgo/#separating-creation-and-configuration-justbeforeeach) that separate creation from configuration (also known as the subject action pattern).
-    - [`BeforeSuite` and `AfterSuite` blocks](http://onsi.github.io/ginkgo/#global-setup-and-teardown-beforesuite-and-aftersuite) to prep for and cleanup after a suite.

+// Some grammars allowed by the C++ implementation are deliberately
+// not implemented here because they are considered a bug by the protobuf team
+// and should not be replicated.

+// The Go implementation should implement a sufficient amount of the C++
+// grammar such that the default text serialization by C++ can be parsed by Go.
+// However, just because the C++ parser accepts some input does not mean that
+// the Go implementation should as well.
+//
+// The text format is almost a superset of JSON except:
+//	* message keys are not quoted strings, but identifiers

+//
+// However, representing a tree as Go literals is difficult to simply do in a

+// objects where the serialization order from the tree-based form is important.
+//
+// The "flattened ordering" is defined as a tree traversal of all enum, message,
+// extension, and service declarations using the following algorithm:

+//		for m in md.Messages:   yield m
+//		for x in md.Extensions: yield x
+//		for m in md.Messages:   yield from VisitMessageDecls(m)

+// Binary serialization
+//
+// This package contains functions to convert to and from the wire format,
+// an efficient binary serialization of protocol buffers.
+//
+// • Size reports the size of a message in the wire format.
+//
+// • Marshal converts a message to the wire format.
+// The MarshalOptions type provides more control over wire marshaling.
+//
+// • Unmarshal converts a message from the wire format.
+// The UnmarshalOptions type provides more control over wire unmarshaling.
+//
+//
+// Basic message operations
+//
+// • Clone makes a deep copy of a message.
+//
+// • Merge merges the content of a message into another.
+//
+// • Equal compares two messages. For more control over comparisons
+// and detailed reporting of differences, see package
+// "google.golang.org/protobuf/testing/protocmp".
+//
+// • Reset clears the content of a message.
+//
+// • CheckInitialized reports whether all required fields in a message are set.
+//
+//
+// Optional scalar constructors
+//
+// The API for some generated messages represents optional scalar fields
+// as pointers to a value. For example, an optional string field has the
+// Go type *string.
+//
+// • Bool, Int32, Int64, Uint32, Uint64, Float32, Float64, and String
+// take a value and return a pointer to a new instance of it,
+// to simplify construction of optional field values.
+//
+// Generated enum types usually have an Enum method which performs the
+// same operation.
+//
+// Optional scalar fields are only supported in proto2.
+//
+//
+// Extension accessors
+//
+// • HasExtension, GetExtension, SetExtension, and ClearExtension
+// access extension field values in a protocol buffer message.
+//
+// Extension fields are only supported in proto2.
+//
+//
+// Related packages
+//
+// • Package "google.golang.org/protobuf/encoding/protojson" converts messages to
+// and from JSON.
+//
+// • Package "google.golang.org/protobuf/encoding/prototext" converts messages to
+// and from the text format.
+//
+// • Package "google.golang.org/protobuf/reflect/protoreflect" provides a
+// reflection interface for protocol buffer data types.
+//
+// • Package "google.golang.org/protobuf/testing/protocmp" provides features
+// to compare protocol buffer messages with the "github.com/google/go-cmp/cmp"
+// package.
+//
+// • Package "google.golang.org/protobuf/types/dynamicpb" provides a dynamic
+// message type, suitable for working with messages where the protocol buffer
+// type is only known at runtime.
+//
+// This module contains additional packages for more specialized use cases.

+// return the protobuf descriptor for the values.
+//
+// The protobuf descriptor interfaces are not meant to be implemented by
+// user code since they might need to be extended in the future to support
+// additions to the protobuf language.
+// The "google.golang.org/protobuf/reflect/protodesc" package converts between
+// google.protobuf.DescriptorProto messages and protobuf descriptors.
+//
+//
+// Go Type Descriptors
+//
+// A type descriptor (e.g., EnumType or MessageType) is a constructor for
+// a concrete Go type that represents the associated protobuf descriptor.
+// There is commonly a one-to-one relationship between protobuf descriptors and
+// Go type descriptors, but it can potentially be a one-to-many relationship.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Type and ProtoReflect.Type accessors respectively
+// return the protobuf descriptor for the values.
+//
+// The "google.golang.org/protobuf/types/dynamicpb" package can be used to
+// create Go type descriptors from protobuf descriptors.
+//
+//
+// Value Interfaces
+//
+// The Enum and Message interfaces provide a reflective view over an
+// enum or message instance. For enums, it provides the ability to retrieve
+// the enum value number for any concrete enum type. For messages, it provides
+// the ability to access or manipulate fields of the message.
+//
+// To convert a proto.Message to a protoreflect.Message, use the
+// former's ProtoReflect method. Since the ProtoReflect method is new to the
+// v2 message interface, it may not be present on older message implementations.
+// The "github.com/golang/protobuf/proto".MessageReflect function can be used
+// to obtain a reflective view on older messages.
+//
+//
+// Relationships
+//
+// The following diagrams demonstrate the relationships between
+// various types declared in this package.

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {
+//       ...
+//     }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+//     Foo foo = ...;
+//     Any any = Any.pack(foo);
+//     ...
+//     if (any.is(Foo.class)) {
+//       foo = any.unpack(Foo.class);
+//     }
+//
+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):
+//       any.Unpack(foo)
+//       ...
+//
+//  Example 4: Pack and unpack a message in Go
+//
+//      foo := &pb.Foo{...}
+//      any, err := ptypes.MarshalAny(foo)
+//      ...
+//      foo := &pb.Foo{}
+//      if err := ptypes.UnmarshalAny(any, foo); err != nil {
+//        ...
+//      }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;
+//     message Person {
+//       string first_name = 1;
+//       string last_name = 2;
+//     }
+//
+//     {
+//       "@type": "type.googleapis.com/google.profile.Person",
+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+//
+type Any struct {
+	state         protoimpl.MessageState
+	sizeCache     protoimpl.SizeCache
+	unknownFields protoimpl.UnknownFields
+
+	// A URL/resource name that uniquely identifies the type of the serialized
+	// protocol buffer message. This string must contain at least
+	// one "/" character. The last segment of the URL's path must represent
+	// the fully qualified name of the type (as in
+	// `path/google.protobuf.Duration`). The name should be in a canonical form
+	// (e.g., leading "." is not accepted).
+	//
+	// In practice, teams usually precompile into the binary all types that they
+	// expect it to use in the context of Any. However, for URLs which use the
+	// scheme `http`, `https`, or no scheme, one can optionally set up a type
+	// server that maps type URLs to message definitions as follows:
+	//
+	// * If no scheme is provided, `https` is assumed.
+	// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+	//   value in binary format, or produce an error.
+	// * Applications are allowed to cache lookup results based on the
+	//   URL, or have them precompiled into a binary to avoid any
+	//   lookup. Therefore, binary compatibility needs to be preserved
+	//   on changes to types. (Use versioned type names to manage
+	//   breaking changes.)
+	//
+	// Note: this functionality is not currently available in the official
+	// protobuf release, and it is not used for type URLs beginning with
+	// type.googleapis.com.
+	//
+	// Schemes other than `http`, `https` (or the empty scheme) might be

+// A Duration represents a signed, fixed-length span of time represented
+// as a count of seconds and fractions of seconds at nanosecond
+// resolution. It is independent of any calendar and concepts like "day"
+// or "month". It is related to Timestamp in that the difference between
+// two Timestamp values is a Duration and it can be added or subtracted
+// from a Timestamp. Range is approximately +-10,000 years.
+//
+// # Examples
+//
+// Example 1: Compute Duration from two Timestamps in pseudo code.
+//
+//     Timestamp start = ...;
+//     Timestamp end = ...;
+//     Duration duration = ...;
+//
+//     duration.seconds = end.seconds - start.seconds;
+//     duration.nanos = end.nanos - start.nanos;
+//
+//     if (duration.seconds < 0 && duration.nanos > 0) {
+//       duration.seconds += 1;
+//       duration.nanos -= 1000000000;
+//     } else if (duration.seconds > 0 && duration.nanos < 0) {
+//       duration.seconds -= 1;
+//       duration.nanos += 1000000000;
+//     }
+//
+// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.
+//
+//     Timestamp start = ...;
+//     Duration duration = ...;
+//     Timestamp end = ...;
+//
+//     end.seconds = start.seconds + duration.seconds;
+//     end.nanos = start.nanos + duration.nanos;
+//
+//     if (end.nanos < 0) {
+//       end.seconds -= 1;
+//       end.nanos += 1000000000;
+//     } else if (end.nanos >= 1000000000) {
+//       end.seconds += 1;
+//       end.nanos -= 1000000000;
+//     }
+//
+// Example 3: Compute Duration from datetime.timedelta in Python.
+//
+//     td = datetime.timedelta(days=3, minutes=10)
+//     duration = Duration()
+//     duration.FromTimedelta(td)
+//
+// # JSON Mapping
+//
+// In JSON format, the Duration type is encoded as a string rather than an
+// object, where the string ends in the suffix "s" (indicating seconds) and
+// is preceded by the number of seconds, with nanoseconds expressed as
+// fractional seconds. For example, 3 seconds with 0 nanoseconds should be
+// encoded in JSON format as "3s", while 3 seconds and 1 nanosecond should
+// be expressed in JSON format as "3.000000001s", and 3 seconds and 1
+// microsecond should be expressed in JSON format as "3.000001s".

+// A Timestamp represents a point in time independent of any time zone or local
+// calendar, encoded as a count of seconds and fractions of seconds at
+// nanosecond resolution. The count is relative to an epoch at UTC midnight on
+// January 1, 1970, in the proleptic Gregorian calendar which extends the
+// Gregorian calendar backwards to year one.
+//
+// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+// second table is needed for interpretation, using a [24-hour linear
+// smear](https://developers.google.com/time/smear).
+//
+// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+// restricting to that range, we ensure that we can convert to and from [RFC
+// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+//
+// # Examples
+//
+// Example 1: Compute Timestamp from POSIX `time()`.
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(time(NULL));
+//     timestamp.set_nanos(0);
+//
+// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+//
+//     struct timeval tv;
+//     gettimeofday(&tv, NULL);
+//
+//     Timestamp timestamp;
+//     timestamp.set_seconds(tv.tv_sec);
+//     timestamp.set_nanos(tv.tv_usec * 1000);
+//
+// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+//
+//     FILETIME ft;
+//     GetSystemTimeAsFileTime(&ft);
+//     UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+//
+//     // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+//     // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+//     Timestamp timestamp;
+//     timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+//     timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+//     long millis = System.currentTimeMillis();
+//
+//     Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+//         .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+//
+// Example 5: Compute Timestamp from current time in Python.
+//
+//     timestamp = Timestamp()
+//     timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard
+// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using
+// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
+// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
+// the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+// ) to obtain a formatter capable of generating timestamps in this format.
