It also induces a lot of XBT code (for + portability sake), that must be maintained too. + * For all these reasons, we killed GRAS. If someone wants to revive it + in the future, don't cry, our git history still remembers of GRAS. + + Documentation: + * Major overhaul. Merge our documentation again as time proved that + splitting it was really not helping our users. + * Further improve the developer documentation to help newcomers + hacking on SimGrid itself.
