hist.*::

	hist.percentage::

		This option control the way to calculate overhead of filtered entries -

		that means the value of this option is effective only if there's a

		filter (by comm, dso or symbol name). Suppose a following example:



		       Overhead  Symbols

		       ........  .......

		        33.33%     foo

		        33.33%     bar

		        33.33%     baz



	       This is an original overhead and we'll filter out the first 'foo'

	       entry. The value of 'relative' would increase the overhead of 'bar'

	       and 'baz' to 50.00% for each, while 'absolute' would show their

	       current overhead (33.33%).
