Arnaldo Carvalho de Melo a64fa198ba perf python scripting: Improve the syscalls-by-pid script 
. Print message at script start telling how to get te summary
. Print the syscall names
. Accept both pid (if numeric) or COMM name

Now it looks like this:

[root@emilia tmp]# perf trace syscall-counts-by-pid
