+
+   Dear reader:
+       This code is based on the premise that if GDB receives a packet
+   from the stub that begins with the character CAPITAL-OH, GDB will
+   echo the rest of the packet to GDB's console / stdout.  This gives
+   the stub a way to send a message directly to the user.  In practice,
+   (as currently implemented), GDB will only accept such a packet when
+   it believes the target to be running (ie. when you say STEP or
+   CONTINUE); at other times it does not expect it.  This will probably
+   change as a side effect of the "asynchronous" behavior.
