 * @brief Those are the SimGrid version of the good ol' assert macro.
 *
 * You can pass them a format message and arguments, just as if it where a printf.
 * It is converted to a XBT_CRITICAL logging request.
 * Be careful: the boolean expression that you want to test should not have side effects, because assertions are
 * disabled at compile time if NDEBUG is set.
