      This new model is more realistic than the previous one, so you
        should consider redoing your old experiments with this model.
      Sorry for the inconvenience.

+ Build System:
+ * Introduce the supernovae compilation mode
+   When compiled that way, the whole SimGrid (or almost) is put in a
+     single compilation unit and compiled in one shoot. 
+  This is to help gcc which has difficulties to inline stuff from one
+     file into another.
+  The speedup seem to be above 15%, althrough more tests are needed on
+     amd64 to confirm that gain.

+      on (amd64/i386/ia64)

+  * Other platforms: windows, AIX and others were not tested for this release
+  
+ Timing report of this version:
+  * Lazy evaluation brings arbitrary speedup (ie, speedup depending on
+    scenario parameters). From 8h to a few seconds in desktop grid settings.
+  * Supernovae brings about 25% speedup on i386.
