1153    The stamp mechanism is more general than the shared state (sstate)
1157    tasks that can be accelerated through the sstate cache.
1164    the sstate cache mechanism adds is a way to cache task output that
1186 usually made available in the form of a shared state (sstate) cache.
1190    For information on variables affecting sstate, see the
1223 It becomes more complicated if everything can come from an sstate cache
1227 from sstate, BitBake does not need the ``do_package`` task data.

1245 The availability of objects in the sstate cache is handled by the
1592 shared state (sstate) code tracks which tasks add which output to the
