 program behaviour.
 The default is to collect a 100 times per second (100 Hz) the
 instruction pointer.
-This is equivalent to the value \[lq]cycles/100\[rq].
+This is equivalent to the value \[lq]100\[rq].
 A value of zero for \f[I]FREQ\f[] effectively disables sampling.
-On some systems, like with recent Linux kernels, it is possible to
-cause the sampling to happen for other events provided by the
-performance counters of the cpu.
