+% This document, when typeset, prompts for the name of a LaTeX auxiliary (.aux) file 
+% and then processes that file, paying attention to 
+% keys that have been cited (via \citation)
+% or defined (via \bibcite).
+% It then prints out diagnostics indicating 
+% * any keys that were cited but never defined,
+% * any keys that were defined but never cited, and
+% * keys that were cited and defined, but not in the same order.
+%
+% BibTeX takes care of such things automatically,
+% so there is little use for such a test when using BibTeX.
+%
+% A separate question: will this file run under revtex4.cls?
+% I can see two lines in my .aux with the potential for problems:
