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