+      examples, tests and demos. Note that running CMake on CGAL is still
+      required in order to generate some configuration files.
+
+
+  o Cone Based Spanners (new package)
+
+    - This package provides algorithms for constructing two kinds of
+      cone-based spanners: Yao graph and Theta graph, given a set of
+      vertices on the plane and the directions of cone boundaries.
