-# This is an example of profiling a specific command or pid.
-# It works by recording the time when a system call is entered
-# exited.
-
-# Usage: prof.stp -c "top -n5"
-# Will start up "top" and after 5 iterations, will exit.
-#
-# Usage: prof.stp -x 3323
-# Will profile pid 3323 until it ^c is hit.
