Hi Ingo,
That's under reviewing, I'll post it as soon as possible. :-) Now I'm considering about it's interface. In the 1st release, I'll use -P "probe-and-arg-definition" option which I suggested perviously, but it is also possible to use -p "event" -a "arg" option which Frederic suggested.
Thank you,
