+The Open MPI Project is an open source MPI-2 implementation that is
+developed and maintained by a consortium of academic, research, and
+industry partners.  Open MPI is therefore able to combine the experise,
+technologies, and resources from all across the High Performance
+Computing community in order to build the best MPI library available.
+Open MPI offers advantages for system and software vendors, application
+developers and computer science researchers.
+
+Open MPI represents the merger between three well-known MPI
+implementations:
+    * FT-MPI from the University of Tennessee
+    * LA-MPI from Los Alamos National Laboratory
+    * LAM/MPI from Indiana University
+with contributions from the PACX-MPI team at the University of
+Stuttgart.  These four institutions comprise the founding members of the
+Open MPI development team.  Each of these MPI implementations excelled
+in one or more areas.  The driving motivation behind Open MPI is to
+bring the best ideas and technologies from the individual projects and
+create one world-class open source MPI implementation that excels in all
+areas.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
