// This is a list of all interfaces that are exposed to workers.
// Please only add things to this list with great care and proper review
// from the associated module peers.

// This file lists global interfaces we want exposed and verifies they
// are what we intend. Each entry in the arrays below can either be a
// simple string with the interface name, or an object with a 'name'
// property giving the interface name as a string, and additional
// properties which qualify the exposure of that interface. For example:
//
// [
//   "AGlobalInterface",
//   { name: "ExperimentalThing", release: false },
//   { name: "ReallyExperimentalThing", nightly: true },
//   { name: "DesktopOnlyThing", desktop: true },
//   { name: "NonB2gOnlyThing", b2g: false },
//   { name: "FancyControl", xbl: true },
//   { name: "DisabledEverywhere", disabled: true },
// ];
//
// See createInterfaceMap() below for a complete list of properties.

// IMPORTANT: Do not change this list without review from
//            a JavaScript Engine peer!
