46: * 1.0 1.1 1.2 1.3 1.4 ECMAv3 1.5
47: * ^ ^

49: * basis for ECMAv1 close to ECMAv2
50: *
51: * where ECMAv3 stands for ECMA-262 Edition 3. See the runtime version enum
52: * JSVersion in jspubtd.h. Code in the engine can therefore count on version
53: * <= JSVERSION_1_4 to mean "before the Third Edition of ECMA-262" and version
54: * > JSVERSION_1_4 to mean "at or after the Third Edition".
55: *
56: * In the unlikely event that SpiderMonkey ever implements JavaScript 2.0, or
57: * ECMA-262 Edition 4 (JS2 without certain extensions), the version number to
58: * use would be near 200, or greater.
59: *
60: * The JS_VERSION_ECMA_3 version is the minimal configuration conforming to
61: * the ECMA-262 Edition 3 specification. Use it for minimal embeddings, where
62: * you're sure you don't need any of the extensions disabled in this version.
63: * In order to facilitate testing, JS_HAS_OBJ_PROTO_PROP is defined as part of
64: * the JS_VERSION_ECMA_3_TEST version.
