+//  This file defines a stack dumping function that can be used for debugging.
+//  It is called whenever the DUMP built-in word is used in the Stacker source.
+//  It has no effect on the stack (other than to print it).
+//
+//  The real reason this is here is to test LLVM's ability to link with
+//  separately compiled software.
