+% Thanks to Andrew Mertz for writing the first draft of the code that
+% produces the \PerlTeX-free \noperlmac\ style file and for testing the
+% final draft; to Phil Kitschen~(?) for pointing out an error in the
+% Hilbert-matrix example; and to Andrei Alexandrescu for providing a few
+% bug fixes. Also, thanks to the many people who have sent me fan mail
+% or submitted bug reports or feature requests. (The
+% \texttt{\string\perldo} macro and the \texttt{--makesty} option were
