General notes regarding labels
==============================

   * Strings appear in quotes except for single word strings.
   * Integers and PDS times do not take quotes.
   * Lists are enclosed within {} type brackets.
   * If a field is unknown, "UNK" may be entered.
   * If a field is not applicable to this file, "N/A" can be used.
   * If a field is unknown at the moment of the creation, but it will be
     know at a later time, "NULL" can be used.
   * Fields can spill freely, with or without white space, onto
     following lines.
