9 The 'children' overhead is calculated by adding all period values of
12 'Children' here means functions that are called from another (parent)
15 It might be confusing that the sum of all the 'children' overhead
19 spread over the children.
64 When the --children option is enabled, the 'self' overhead values of
66 calculate the 'children' overhead. In this case the report could be
70 Children Self Symbol
96 'children' overhead of 'bar', 'main' and '\_\_libc_start_main'.
98 'children' overhead of 'main' and '\_\_libc_start_main'.
