+         Hist triggers allow one or more arbitrary trace event fields to be
+         aggregated into hash tables and dumped to stdout by reading a
+         debugfs/tracefs file. They're useful for gathering quick and dirty
+         (though precise) summaries of event activity as an initial guide for
+         further investigation using more advanced tools.
