+Depending on the context, you may see some parts of this process as
+less important, but you should pay close attention if you want to be
+confident in the results coming out of your simulations. In
+particular, you should not trust blindly your results but always
+strive to double-check them. Likewise, you should question the realism
+of your input configuration, and we even encourage you to doubt (and
+check) the provided performance models.
+
+To ease such questionning, you really should logically separate these
+parts in your experimental setup. It is seen as a very bad practice to
+merge the application, the platform and the deployment all together.
+SimGrid is versatile and your milleage may vary, but you should start
+with your Application specified as a C++ or Java program, using one of
+the provided XML platform file, and with your deployment in a separate
+XML file.
