add color for "test", not sure it's mandatory, but it won't hurt
Merge branch 'master' of git+ssh://scm.gforge.inria.fr//gitroot//simgrid/simgrid
forgot a comma ...
Rewrote smpi_sleep() and smpi_usleep() so that:
	1. the code is not duplicated but shared in a static private function
	2. sleeping is done via an actual simcall_process_sleep rather than a bogus computation

Augmented SMPI tracing to allow tracing of sleep events
Merge branch 'master' of git+ssh://scm.gforge.inria.fr//gitroot/simgrid/simgrid
Added a --cfg="smpi/simulation_computation" to smpirun. The default
value is "yes", meaning that SMPI will benchmark computational parts
of the simulation application and simulate them using smpi_execute(), as
it's always been done in the past.

Disabling the simulation of computation is useful when smpirunning an "application"
that is in fact doing a "live replay" of another MPI app (e.g., ScalaTrace's replay tool, various on-line simulators that run an app at scale). In this case the computation due to the replay logic
should be be simulated by SMPI.

For the time being, for smpirunning such an "application", the approach is:
	1. use --cfg="smpi/simulation_computation:no"
	2. add calls to smpi_execute() in the "application"
Fix use of wrong variable
Merge branch 'master' of git+ssh://scm.gforge.inria.fr//gitroot/simgrid/simgrid
Fix warning about duplicate typedef.
Add check for error.
Fix dead assignments.

That's when a value stored in a variable is never used.
Don't try to kill non-existing process (*process == NULL).
Set return value.
document the smpi/simulation_computation option and list it in the
index (with the one on privatization too)
updating ignore patterns-list should be complete now
Added documentation of the  --cfg="smpi/simulation_computation" feature of mpirun

merge Fred and Henri description of the same stuff
Add a function returning an instance of fat tree
The tag cluster accepts the topology fat_tree
