/* this benchmark recursively builds a pipeline and meassures the time to go

* from ready to paused.
|

* The graph size and type can be controlled with a few commandline args:
|
||||
* -d depth: is the depth of the tree
|
||||
* -c children: is the number of branches on each level
|
||||
* -f <flavour>: can be a=udio/v=ideo and is conttrolling the kind of elements
|

* that are used.
