// Package protodesc provides functionality for converting
// FileDescriptorProto messages to/from protoreflect.FileDescriptor values.
//
// The google.protobuf.FileDescriptorProto is a protobuf message that describes
// the type information for a .proto file in a form that is easily serializable.
// The protoreflect.FileDescriptor is a more structured representation of
// the FileDescriptorProto message where references and remote dependencies
// can be directly followed.

// first value in the associated enum (or zero if the also enum dependency
// is also unresolvable). The protoreflect.FieldDescriptor.DefaultEnumValue

// • Resolving the extended message type for an extension field.
// • Resolving the input or output message type for a service method.
//
// If the unresolved dependency uses a relative name,
