Warning : 
   The input data file format for 'contour' has been changed (4/9/90)
   to conform with the format used in drawplot and pdraw.

   Instead of the header being 
      xmin, xlength, ymin, ylength....
   the header now goes as 
      xmin, xmax, ymin, ymax

   To plot old SPLAT files, use the -old option.
   The latest version of SPLAT (mascot:~ktoh/bin/splat) has been modified
      to use this new header format.
   See the man pages for more details.
