+				<para> 
+            SFCGAL is a C++ wrapper  library around CGAL that provides advanced 2D and 3D functions. 
+            For robustness, geometry coordinates have an exact rational number representation.

-          TODO Install part
+            Installation instructions of the library can be found on SFCGAL home page (http://www.sfcgal.org).
