+%% Generates a string for Gmsh Line Loop format.
+%%
+%% The third elementary entity is the surface. In order to define a
+%% simple rectangular surface from defined lines, a
+%% line loop has first to be defined. A line loop is a list of
+%% connected lines, a sign being associated with each line (depending
+%% on the orientation of the line). @var{id} is an indentifier for the loop.
+%% @var{nl} is the number of lines in the loop. @var{lns} is the list of lines.
