+<li><b>To remove initial central point</b> - TetMesh-GHS3D adds an internal point
+at the centre of gravity of the bounding box in order to speed up and to simplify
+the meshing process. It is however possible for TetMesh-GHS3D to refrain from creating
+this point by using the command line option -no initial central point. This can be
+particularly useful to generate a volume mesh without internal points at all, and in some rare cases,
+to help the boundary regeneration phase when it failed with the standard options (for example when
+one dimension of the domain is large compared to the other two, with a ratio of 20 or more).
+Use this option when the boundary regeneration failed with the standard parameters and before using
+the recovery version (command line option -C).
+Note: when using this option, the speed of the meshing process may decrease, and quality may change.
+Note: the boundary regeneration may fail with this option, in some rare cases.</li>
