+
+The program will append to an existing shape file or it will
+create a new file if needed.
+Only the items in the first output file will be preserved.
+When an item does not match with the append theme then the item
+might be placed to an existing item at the same position and type.
+  OTHER FUNCTIONS:
+  - Select a group of shapes from a comma separated selection list.
+  - UnSelect a group of shapes from a comma separated selection list.
+  - Clip boundary extent or by theme boundary.
+      Touch writes all the shapes that touch the boundary.
+      Inside writes all the shapes that are completely within the boundary.
+      *(N/A) Cut will cookie-cut shapes that are touching the boundary.
+      Boundary clips are only the min and max of a theme boundary.
+      *(N/A) Polygon clips use the polygons within a theme.
+  - Erase boundary extent or by theme boundary.
+      Erase is the direct opposite of the Clip function.
+  - Change coordinate value units between meters and feet.
+      There is no way to determine the input unit of a shape file.
+      Skip this function if the shape file is already in the correct unit.
+      Clip and Erase will be done before the unit is changed.
+      A shift will be done after the unit is changed.
+  - Shift X and Y coordinates.
+
+Finally, There can only be one select or unselect in the command line.
+         There can only be one clip or erase in the command line.
+         There can only be one unit and only one shift in the command line.
+EX: shputils in.shp out.shp  CLIP 10 10 90 90 Touch  UNIT Feet  SHIFT 40 40
+    shputils in.shp out.shp  SELECT countycode 3,5,9,13,17,27
