+// call_stack.h: A call stack comprised of stack frames.
+//
+// This class manages a vector of stack frames.  It is used instead of
+// exposing the vector directly to allow the CallStack to own StackFrame
+// pointers without having to publicly export the linked_ptr class.  A
+// CallStack must be composed of pointers instead of objects to allow for
+// CPU-specific StackFrame subclasses.
+//
+// By convention, the stack frame at index 0 is the innermost callee frame,
+// and the frame at the highest index in a call stack is the outermost
+// caller.  CallStack only allows stacks to be built by pushing frames,
+// beginning with the innermost callee frame.
