I would like to have a similar user tool for Intel PEBS data.

I have some hacks currently to dump more data from the PEBS record and
it's useful for some situations. I was actually thinking of adapting
Robert's tool, but integrating it into other tools is fine too.

Sometimes a "perf print-samples" to print individual samples
would be useful too  (it's already possible with -R, but very unfriendly
without post processing)
