8 * This file contains the MC replay/record functionality.
9 * The recorded path is written in the log output and can be replayed with MC disabled
10 * (even with a non-MC build) using `--cfg=model-check/replay:$replayPath`.
12 * The same version of SimGrid should be used and the same arguments should be
13 * passed to the application (without the MC specific arguments).
