+ * <h2>Description</h2>
+ * This module implements a series of system benchmarks. The benchmarks
+ * are useful as a stress test and as a reference when comparing
+ * ChibiOS/RT with similar systems.<br> Objective of the test sequence
+ * is to provide a performance index for the most critical system
+ * subsystems. The performance numbers allow to discover performance
+ * regressions between successive ChibiOS/RT releases.
