 * - LASRROTT.ZIP consists of six levels, three regular and three comm-bat,
     for Rise of the Triad.  The levels were originally released back in 1995
     as in a special deluxe edition of the shareware game that was distributed
     by LaserSoft.
   - TED5.ZIP and TED5LITE.ZIP is the level editor used on the Keen games,
     Wolfenstein 3D, Rise of the Triad, and several others.  It was made
     available for the purpose of making new Rise of the Triad levels.  It is
     available both for free downloading and on the Extreme Rise of the
     Triad CD.  The editor is provided "as is;" Apogee cannot offer technical
     support on it.  Ted5 Lite contains just the editor; Ted5 comes with extra
     documentation, samples, and other files.
   - OHIORTC.ZIP is a set of four levels specially created by Apogee for a
     contest at a college in Ohio.
   - TVREG_S3.ZIP is an executable for the registered version of Terminal
     Velocity that is optimized for S3 Virge chipset video cards.  It requires
     the registered version 1.2 of the game and a S3 Virge video card.  It is
     distributed by Terminal Reality, Inc., and not by 3D Realms.
   - LAMEDUKE.ZIP is an early beta version of Duke Nukem 3D, released "as is,"
     in honor of Duke3D v1.0's one year anniversary, purely for the curious
     amusement of the game's fans.
