sortshp - sort a Shape data set

sortshp  sorts a Shape data set based on a single column in ascending or descending order. Supports INTE‐
       GER, DOUBLE and STRING column types. Useful for prioritizing shapes for rendering and/or labeling.

       The idea here is that if you know that you need to display a certain attribute classed by a certain  val‐
       ue, it will be faster for MapServer to access that value if it is at the beginning of the attribute file.

       This  example  uses  a  roads  file  ('roads_ugl')  that  has a field with road classes in integer format
       ('class1').

              sortshp roads_ugl roads-sort class1 ascending

       Result:
              A new Shape data set named 'roads-sort.shp' is created with shapes sorted in ascending order,  ac‐
              cording to the values in the 'class1' field.
