+These are the source codes for the conversion
+ of a .xml mesh to/from a (p,e,t) mesh.
+
+You need dolfin to compile and execute it:
+
+mkoctfile xml2oct.cc -ldolfin
+mkoctfile oct2xml.cc -ldolfin
+
+Under Octave you can run the following example 
+for xml2oct with 
+
+mesh = xml2oct("dolfin_fine.xml.gz");
+msh2p_mesh(mesh);
+
+(the mesh dolfin has been taken
+from the Fenics website, author: A.Logg)
+
+Under Octave you can run the following example 
+for xml2oct with 
+
+mesh = msh2m_structured_mesh(linspace(0,1,10),linspace(0,1,20),1,[0 1 2 3]);
+oct2xml(mesh,"my_output_name");

+if you occur in this error:
+octave: symbol lookup error: /usr/lib/openmpi/lib/openmpi/mca_paffinity_linux.so: undefined symbol: mca_base_param_reg_int
+
+you can solve it with the following command:
+export LD_PRELOAD=/usr/lib/openmpi/lib/libmpi.so
