+
+File: dir Node: Top This is the top of the INFO tree
+
+ This (the Directory node) gives a menu of major topics.
+ Typing "q" exits, "?" lists all Info commands, "d" returns here,

++ pointers that could be used to further corrupt arbitrary memory
++ locations, and the (4) omission of instrumentation code from some
