This is a track definition file.  The computer will only read the above
lines, so any kind of commentary can go down here.
The arrangement above is:

 NSEG - the number of track segments
 X_MAX  Y_MAX - the maximum value of X that needs to be displayed,
                feet.  (followed by the same for Y)
 width - width of race course, feet

 TRK_STRT_X     TRK_STRT_Y    - coordinates of outer rail starting point, feet
 SCORE_BOARD_X  SCORE_BOARD_Y - coordinates of scoreboard upper left corner
 LDR_BRD_X      LDR_BRD_Y     - coordinates of leader board upper left corner
 LOTIX          LOTIY         - coordinates of start of track length message
 FINISH                       - fraction of 1st segment prior to finish line

 radius        length         - NSEG repetitions of segment radius, length:
 radius        length         - (0 radius means a straightaway, with length
 radius        length         -  in feet.  Length of curves is in radians.)
