A common config for me is to use "-x sched_info" since those sched_info stats seem to always be moving rapidly and can cloud stats that are more interesting (to me, anyway). > > Let me know if you have any questions.

Hi All, I have released a new version (v0.5) which fixes a compile error on some platforms (like Mandriva, RHEL, and opensuse-factory) that did not like the usage of operator/ in boost::filesystem::path code. v0.5 is now fully supported on all of the original platforms that v0.2 worked on.
