+Usage: %s [options]
+
+Options:
+  -h, --help              print this help and exit
+  -c, --config=PATH       use PATH as the test configuration
+  -s, --samples=TIME      run test for TIME seconds (defaults to 30)
+                          (or indefinitely if set to inf, or infinity)
+
+Cleanup:
+  --clean                 delete all previous test and preseed artifacts
+  --clean-tests           delete all previous test artifacts
+  --clean-preseeds        delete all previous preseed artifacts
+
+Debugging Options:
+  --debug                 run each component under a debugger
+                          (likely requires a Debug build to be useful)
+  --profile               run each component under perf
+                          (likely requires a Profiling build to be useful)
+  --leak-check            run each component under valgrind
+
+  -d, --debugger=CMD      specify the debugger CMD
+                          ("gdb" and "rr" are short-cuts for sensible defaults
+                          for those debuggers)
+
+Note: --debug, --profile, and --leak-check are mutually-exclusive
