+    (description
+     "stress-ng stress-tests a computer system by exercising both physical
+subsystems as operating system kernel interfaces.  It can stress the CPU, 
cache,
+disk, memory, socket and pipe I/O, scheduling, and much more, in various
+selectable ways.  This can trip hardware issues such as thermal overruns as 
well
+as operating system bugs that occur only when a system is being thrashed hard.
+
+You can also measure test throughput rates, which can be useful to observe
+performance changes across different operating system releases or types of
+hardware.  However, stress-ng is not a benchmark.  Use it with caution: some of
+the tests can make poorly designed hardware run dangerously hot or make the
+whole system lock up.
+
+Compared to its inspiration, @command{stress}, @command{stress-ng} offers many
+additional options such as the number of bogo operations to run, execution
+metrics, verification of memory and computational operations, and considerably
+more stress mechanisms.")
