_D_e_t_a_i_l_s:

     Most functions within 'RSurvey' are accessible within this GUI. 
     The text file format of survey data is described in 'readFile'. 
     The text file representation of a polygon is of the following
     format:

      <number of contours>
      <number of points in first contour>
      <hole flag>
      x1 y1
      x2 y2
      ...
      <number of points in second contour>
      <hole flag>
      x1 y1
      x2 y2
      ...

      The hole flag is either 1 to indicate a hole, or 0 for a regular
     contour.  See 'read.polyfile' within the 'gpclib' package for
     details.
