We'll use it to ask for extra config files to be loaded, profile like stuff that will be used first to make 'perf trace' mimic 'strace' output via a 'perf strace' command that just sets up 'perf trace' output. At some point it'll be used for regression tests, where we'll run some simple commands like: perf strace ls > perf-strace.output strace ls > strace.output And then do some mutable syscall arg aware diff like tool to deal with arguments for things like mmap, that change at each execution, to be first ignored and then properly tracked when used accoss multiple syscalls.
