[openbox] The state of the art in tiling with Openbox

[Antoine]

Hello!
I'd like to know what are the current options to achieve tiling with 
Openbox. I personally use Pytyle (the deprecated first version) and it's 
really useful when tiling is needed. I heard about Pytyle3, but I can't 
find any documentation (especially how to undecorate everything when 
tiling is activated, or how to leave a margin between tiled windows). 
What do you use? Are there some other options?

Cheers,
Ant
