-SimGrid is a simulator of distributed computer systems. It can be used
-to either assess abstract algorithms, or to profile and debug real
-distributed applications. SimGrid enables studies in the domains of
-(data-)Grids, Clusters, IaaS Clouds, High Performance Computing,
-Volunteer Computing and Peer-to-Peer.
-
-SimGrid is a feature rich framework, with many options and
-possibilities. Hopefully its documentation will help you getting at
-full gear. But nothing's perfect, and this documentation is really no
-exception here. Please help us improving it by reporting the issues
-that you see.
-
-SimGrid is a Free Software distributed under the LGPL licence. It
-means that you are welcome to use it as you wish, or even to modify
-and distribute your version (as long as your version is as free as
-ours). It also means that SimGrid is developed by a vivid community of
-users and developers. We hope that you will join the community!
-
-SimGrid beneficied of many fundings from various research instances,
-including: the ANR, Inria, CNRS, University of Lorraine, University of
-Hawai'i at Manoa, ENS Rennes and many others. Thanks to our generous
-donators! SimGrid would not exist without the research that they funded.

+Technically speaking, SimGrid is a library. It is neither a graphical
+interface nor a command-line simulator running user scripts. The
+interaction with SimGrid is done by writing programs with the exposed
