 * This is the JavaScript error message file.
 *
 * The format for each JS error message is:
 *
 * MSG_DEF(<SYMBOLIC_NAME>, <ARGUMENT_COUNT>, <EXCEPTION_NAME>,
 *         <FORMAT_STRING>)
 *
 * where ;
 * <SYMBOLIC_NAME> is a legal C identifer that will be used in the
 * JS engine source.
 *
 * <ARGUMENT_COUNT> is an integer literal specifying the total number of
 * replaceable arguments in the following format string.
 *
 * <EXCEPTION_NAME> is an exception index from the enum in jsexn.c;
 * JSEXN_NONE for none.  The given exception index will be raised by the
 * engine when the corresponding error occurs.
 *
 * <FORMAT_STRING> is a string literal, optionally containing sequences
 * {X} where X  is an integer representing the argument number that will
 * be replaced with a string value when the error is reported.
 *
 * e.g.
 *
 * MSG_DEF(JSMSG_NOT_A_SUBSPECIES, 2, JSEXN_NONE,
 *         "{0} is not a member of the {1} family")
 *
 * can be used:
 *
 * JS_ReportErrorNumberASCII(JSMSG_NOT_A_SUBSPECIES, "Rhino", "Monkey");
 *
