// Options

// Each of the definitions above may have "options" attached.  These are
// just annotations which may cause code to be generated slightly differently
// 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
//   to automatically assign option numbers.

  // - 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 descendant.  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.
  // - Code which tries to interpret locations should probably be designed to
  //   ignore those that it doesn't understand, as more types of locations could

// Our implementation hinges around a powerful primitive which we call MultiOp. All other database

// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
// may apply to the same or different entries in the database. All tests in the guard are applied and
// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
// it executes f op (see item 3 below).
// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
// lookup operation, and applies to a single database entry. Two different operations in the list may apply
// to the same or different entries in the database. These operations are executed
// if guard evaluates to
// true.
// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.
