A propos my previous question about showing labels, Donald Arsenau 
suggested using the package showkeys, which works beautifully.  Now I have 
another question.  It seems to me that there is a package that scans a 
file and finds unused macros, but I couldn't find it at CTAN.  Is there 
such a package?
