/*
 * execsnoop-nd.stp	Trace process exec()s with arguments.
 *			For Linux, uses SystemTap (non-debuginfo).
 *
 * This is useful for identifying new process creation, provided it follows the
 * fork()->exec() sequence. New processes that only fork will not be seen; catch
 * those by tracing fork() or using the process.begin probe.
 *
 * USAGE: ./execsnoop-nd.stp
 *
 * This is a basic version of execsnoop.
