+%% @deftypefn {Function File} @var{str} =  poointGeo (@var{n}, @var{xyz}, @var{l})
+%% Generates a string for Gmsh Point format.
+%%
+%% Gmsh's simplest `elementary entity', a `Point'. A Point is defined by a list
+%% of five numbers: @var{n} the identificator, @var{xyz} three coordinates (X, Y
+%% and Z), and a characteristic length @var{l} that sets the target element size
+%% at the point:
+%% The distribution of the mesh element sizes is then obtained by
+%% interpolation of these characteristic lengths throughout the
+%% geometry.
