This is a quit display system.

many people:

It has the distinction, as you can see in the screenshots, to collect the netsplits in a few lines.
Why use this code? This will prevent you to have dozens of identical lines in case of netplits with a better rendering.
I put 3 alias just under that allow you to adjust my system at your convenience.
However i didn't setup the normal quits you have to do it by yourself.
The text is in French but it is very easy to change
