+altered on the fly.  The implementation involves a pile of lambda-calculus and
+list-handling macros of an incredibly obtuse nature.  The TUGboat paper serves
+as a manual for the macros.  Having said all of which, confidence is enhanced
+by the knowledge that the TeX code was formally verified.")
