are synonyms provided by aestheticism). You can provide several of those
arguments to change the setting of several categories, they will be applied
from left to right. So,
-\verbatim --xbt-log="root.thres=debug root.thres=critical"\endverbatim
+\verbatim --xbt-log="root.thres:debug root.thres:critical"\endverbatim
should disable any logging.
Note that the quotes on above line are mandatory because there is a space in
the argument, so we are protecting ourselves from the shell, not from SimGrid.
We could also reach the same effect with this:
-\verbatim --xbt-log=root.thres=debug --xbt-log=root.thres=critical\endverbatim
+\verbatim --xbt-log=root.thres:debug --xbt-log=root.thres:critical\endverbatim
