    + 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%).
