 122 While tracing there were numerous system calls made, including 173 open64()'s,
 123 and 77 stat64()'s.  There were also many functions called, including 22 each
 124 of abspath, isabs, and normpath by the posixpath.py library.
 125
 126 This script can provide an insight to how an application is interacting
 127 with the system, by providing both application function calls and
 128 system calls in the same output.
