After a brief test run, I'm very impressed. It built and installed easily, there was a great example on the man page, and the results (from my mostly idle system :-) were very detailed.
Compared to gprof (which I believe comes with gcc), this program plays in another league. Stuff like knowing which kernel functions have taken most time during your program's run, and getting to know how large part of the time your X app spends in the X libraries is invaluable.
Great work guys, keep it up!
