+// 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.
+// Consult the individual package documentation for details.

+// Package protoreflect provides interfaces to dynamically manipulate messages.
+//
+// This package includes type descriptors which describe the structure of types
+// defined in proto source files and value interfaces which provide the
+// ability to examine and manipulate the contents of messages.
+//
+//
+// Protocol Buffer Descriptors
+//
+// Protobuf descriptors (e.g., EnumDescriptor or MessageDescriptor)
+// are immutable objects that represent protobuf type information.
+// They are wrappers around the messages declared in descriptor.proto.
+// Protobuf descriptors alone lack any information regarding Go types.
+//
+// Enums and messages generated by this module implement Enum and ProtoMessage,
+// where the Descriptor and ProtoReflect.Descriptor accessors respectively
+// 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.
