+SUMMARY="Polygon Clipping and Offsetting Library"
+DESCRIPTION="Clipper2 is an open source freeware software library (written in C++, C# and Delphi \
+Pascal) that performs line and polygon clipping, and offsetting.
+
+Clipper2 is a major update of my original Clipper library which I'm now calling Clipper1. \
+Clipper1 was written over 10 years ago and although it still works very well, Clipper2 is much \
+better. And Clipper2 has all the features of Clipper1 that sets Clipper apart from other polygon \
+clipping libraries, including:
+
+* being able to clip complex self-intersecting polygons
+* support polygons with multiple filling rules (EvenOdd, NonZero, Positive, Negative)
+* is numerically robust, and
+* is free to use in both freeware and commercial applications"
