+%% This style file is based on original work by Olivier Verdier

+%%
+%% Modified for ANS by Anders Logg <logg@simula.no>, 2011.
+%%
+%% Modified by Hans Petter Langtangen <hpl@simula.no>, 2011, to
+%% have pairs c++ (with C++ title) and c++:nt (no title),
+%% python and python:nt, etc. (It is not always desirable to
+%% have a title with the language.) Added Cython and Fortran style.
