+igl_lib is a lightweight C++ for mesh processing
+
+Example1.cpp: 
+- Load/save a mesh
+- Compute face and edge topology
+- Compute the cotan matrix of the loaded mesh
+
+Example2.cpp:
+- Show how it is possible to send/receive matrices to/from matlab
+in order to use the matlab functions in the igl_toolbox
+
+Tu run example2 you need matlab and to properly configure your PATH and DYLD_PATH.
+See runexample2.sh for an example.
