[O] showing children in agenda

[Ken Mankoff]

If I have a task with children, and the parent is SCHEDULED today so 
it is showing up in the agenda, is there a way to make children 
automagically show up?

My specific use case is that I have a parent task, broken down by 
sub-tasks as children. I only schedule the parent rather than all 
the sub-tasks, but it would be nice when the parent shows up in the 
agenda that I can see the children and easily set estimates and 
clock in as I see them.

Is there some method to achieve this, or do I need to set each child 
as SCHEDULED and TODO also?

Thanks,

  -k.
