Hello Thomas, thanks for this contribution.

Could you provide some examples to see this in action ? There are lots of existing one in the log directory, you can add yours in there.

Also we are not very confident to change the default and historic behavior... You should add a parameter to activate your new behavior, this parameter would disabled it by default.

Oh, why is it closed? I did not see this comment, so sorry for not responding earlier.

As you see in the code, my additions are configurable. The only thing is that default behaviour is not disabled. I can add this if wanted.

Hello Thomas,
Very sorry, I did not close explicitly this PR...
I delete the develop branch though, so it might have triggered a close of all PR on this branch ?
You can open a new PR as a copy of this one, but don't forget to add examples as requested on may last year O:)

Why removing the develop branch? Isn't there anymore development on this going to happen?

When we migrated our code to GitHub during summer 2018, we decided to use GitFlow for our modules as well as in the iTop repo.
But two years later we see that modules don't need it at all ! So we're sticking with only 1 branch, that is master. Some modules may have a support branch when needed, but there are very few of them.
