I sincerely apologize for my md-mm. Also, I forgot about PUPIL, which
I heard about some time ago.
While interfacing with Gaussian is of little interest for me, hearing
about interfacing with nwchem and gamess is of great interest. Why not
mpqc? It is fast. It was born parallelized. It is GNU. It is written
in C. It is object oriented. No recent density functional and no
excited states but supporting it by linking amber to it might break
Thanks indeed and again very sorry for my typo.
