%D Let's get rid of this one: 

\def\wlog#1{} 

%D Just for tracing purposes we set:

\tracingstats=1

%D We don't like outer commands, and we always want access 
%D to the original \type {\input} primitive. 

\let\normalouter = \outer  \let\outer\relax
\let\normalinput = \input  

%D We need to make sure that we start up in \DVI\ mode, so, 
%D after testing for running \PDFTEX, we default to \DVI.  

\ifx\pdftexversion\undefined \newcount\pdfoutput \fi \pdfoutput=0

%D To circumvent dependencies, we can postpone certain 
%D initializations to dumping time, by appending them to the 
%D \type {\everydump} token register. 

\newtoks \everydump 

\let\normaldump \dump
