 * MESSAGE CATALOG FILE FORMAT.
 *
 * The NetBSD message catalog format is similar to the format used by
 * Svr4 systems.  The differences are:
 *   * fixed byte order (big endian)
 *   * fixed data field sizes
 *
 * A message catalog contains four data types: a catalog header, one
 * or more set headers, one or more message headers, and one or more
 * text strings.
