USAGE: syscalltimes [-n pname]... [-p pid]... [-u username]... [-c 'process']
[-v]... [-t] [-h]
-n pname # filter by this process name
-p pid # filter by this process ID
-u username # filter by this user
-c 'process' # run 'process' then exit to show totals
-t # print totals (default with filters: OFF
default without filters: ON)
-v # print verbose output during SystemTap module creation
-h # print this help text
NOTE: This script can take long time to build. Use -v[vv] to monitor
the module creation and build process.
