Hi guys,
I am using sauerbraten on a debian system.
I notice that if launched by command line, sauer output all the in-game info, in "real time" to the terminal, something like:

you fragged player_1
player_2 stole enemy flag
player_3 fragged player_4
you been fragged by player_2

and much more.
But if I try to grep it, like:

$>sauerbraten | grep you

it won't do what expected!
Simply won't output nothing until i quit the game, then all the "grepped" infos came out together.
That was the first attempt to bash scripting the sauer output to show something cool (and maybe useful) on the second screen I have.
Seems that grep cannot process the sauer output stream one line a time, but I can't figure why.
Someone can help me undestand what's wrong and if possible to fix it?
