+DESCRIPTION="
+GEOS is a C++ port of the Java Topology Suite (JTS). As such, it aims to \
+contain the complete functionality of JTS in C++. This includes all the \
+OpenGIS Simple Features for SQL spatial predicate functions and spatial \
+operators, as well as specific JTS enhanced topology functions.
