+%description
+Open MPI is an open source, freely available implementation of both the
+MPI-1 and MPI-2 standards, combining technologies and resources from
+several other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI) in
+order to build the best MPI library available. A completely new MPI-2
+compliant implementation, Open MPI offers advantages for system and
+software vendors, application developers, and computer science
+researchers. For more information, see http://www.open-mpi.org/ .
