+Welcome to the SimGrid project!
+
+SimGrid is a scientific instrument to study the behavior of
+large-scale distributed systems such as Grids, Clouds, HPC or P2P
+systems. It can be used to evaluate heuristics, prototype applications
+or even assess legacy MPI applications.
+
+More documentation is included in this archive (doc/html/index.html)
+or online at http://simgrid.gforge.inria.fr/
+
+In any case, you may want to subscribe to the user mailing list
+(http://lists.gforge.inria.fr/mailman/listinfo/simgrid-user). There,
+you can find answers to your questions, or simply discuss with people
+doing the same kind of research than you do, in an active and friendly
+community.
+
+Thanks for using our software. Please do great things with it and tell
+the world about it. Tell us, too, because we love to have positive
+feedback.
+
+Cheers,
+Da SimGrid Team.
