This is a sampling profiler that uses a kernel module, sysprof-module, to generate stacktraces which are then interpreted by the userspace program "sysprof". - The profiler uses a kernel module, so it is Linux specifc - There is no auto* stuff. Just type "make" and hope for the best. - You need gtk+ 2.4.0 or better, and you need libglade - Thanks to Kristian Høgsberg, it now works on the 2.6 kernel. Søren
