8 * This file contains the MC replay/record functionnality.
9 * A MC path may be recorded by using ``-cfg=model-check/record:1`'`.
10 * The path is written in the log output and an be replayed with MC disabled
11 * (even with an non-MC build) with `--cfg=model-check/replay:$replayPath`.
13 * The same version of Simgrid should be used and the same arguments should be
14 * passed to the application (without the MC specific arguments).
