// Options
// Each of the definitions above may have "options" attached. These are

// or may contain hints for code that manipulates protocol messages.
//
// Clients may define custom options as extensions of the *Options messages.
// These extensions may not yet be known at parsing time, so the parser cannot
// store the values in them. Instead it stores them in a field in the *Options
// message called uninterpreted_option. This field must have the same name
// across all *Options messages. We then use this field to populate the
// extensions when we build a descriptor, at which point all protos have been
// parsed and so all extensions are known.
//
// Extension numbers for custom options may be chosen as follows:
// * For options which will only be used within a single application or
// organization, or for experimental options, use field numbers 50000
// through 99999. It is up to you to ensure that you do not use the
// same number for multiple options.
// * For options which will be published and used publicly by multiple
// independent entities, e-mail protobuf-global-extension-registry@google.com
// to reserve extension numbers. Simply provide your project name (e.g.
// Objective-C plugin) and your project website (if available) -- there's no
// need to explain how you intend to use them. Usually you only need one
// extension number. You can declare multiple options with only one extension
// number by putting them in a sub-message. See the Custom Options section of
// the docs for examples:
// https://developers.google.com/protocol-buffers/docs/proto#options
// If this turns out to be popular, a web service will be set up

// Let's look at just the field definition:
// optional string foo = 1;
// ^ ^^ ^^ ^ ^^^

// [e,f) [ 4, 0, 2, 0, 1 ] The name (foo).
// [g,h) [ 4, 0, 2, 0, 3 ] The number (1).
//
// Notes:
// - A location may refer to a repeated field itself (i.e. not to any
// particular index within it). This is used whenever a set of elements are
// logically enclosed in a single code segment. For example, an entire
// extend block (possibly containing multiple extension definitions) will
// have an outer location whose path refers to the "extensions" repeated
// field without an index.
// - Multiple locations may have the same path. This happens when a single
// logical declaration is spread out across multiple places. The most
// obvious example is the "extend" block again -- there may be multiple
// extend blocks in the same scope, each of which will have the same path.
// - A location's span is not always a subset of its parent's span. For
// example, the "extendee" of an extension declaration appears at the
// beginning of the "extend" block and is shared by all extensions within
// the block.
// - Just because a location's span is a subset of some other location's span
// does not mean that it is a descendent. For example, a "group" defines
// both a type and a field in a single declaration. Thus, the locations
// corresponding to the type and field and their components will overlap.

// ignore those that it doesn't understand, as more types of locations could
// be recorded in the future.
