+stress-ng will stress test a computer system in various
+selectable ways. It was designed to exercise various
+physical subsystems of a computer as well as the various
+operating system kernel interfaces. Stress-ng features:
+
+* Over 200 stress tests
+* 70 CPU specific stress tests that exercise floating point,
+  integer, bit manipulation and control flow
+* Over 20 virtual memory stress tests
+
+stress-ng was originally intended to make a machine work
+hard and trip hardware issues such as thermal overruns as
+well as operating system bugs that only occur when a system
+is being thrashed hard. Use stress-ng with caution as some
+of the tests can make a system run hot on poorly designed
+hardware and also can cause excessive system thrashing which
+may be difficult to stop.
+
+stress-ng can also measure test throughput rates; this can
+be useful to observe performance changes across different
+operating system releases or types of hardware. However, it
+has never been intended to be used as a precise benchmark
+test suite, so do NOT use it in this manner.
+
+Running stress-ng with root privileges will adjust out of
+memory settings on Linux systems to make the stressors
+unkillable in low memory situations, so use this
+judiciously. With the apropriate privilege, stress-ng can
+allow the ionice class and ionice levels to be adjusted,
+again, this should be used with care.
+
+One can specify the number of processes to invoke per type
+of stress test; specifying a negative or zero value will
+select the number of online processors as defined by
+sysconf(_SC_NPROCESSORS_ONLN).
+
+NOTE ON VM TESTS
+
+Since the memory being exercised is virtually mapped then
+there is no guarantee of touching page addresses  in  any
+particular  physical  order.  These workers should not be
+used to test that all the system's memory is working cor‐
+rectly either, use tools such as memtest86 instead.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
