49 
50  A TARGET is an interface between the debugger and a particular
51  kind of file or process. Targets can be STACKED in STRATA,
52  so that more than one target can potentially respond to a request.
53  In particular, memory accesses will walk down the stack of targets
54  until they find a target that is interested in handling that particular
55  address. STRATA are artificial boundaries on the stack, within
56  which particular kinds of targets live. Strata exist so that
57  people don't get confused by pushing e.g. a process target and then
58  a file target, and wondering why they can't see the current values
59  of variables any more (the file target is handling them and they
60  never get to the process target). So when you push a file target,
61  it goes into the file stratum, which is always below the process
62  stratum. */
