+ 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%).
