% Karl Berry and others, 2004. Public domain.
%
% This file is not used in TeX Live 2005.
%
% For TeX Live 2004, we started building the "latex" format with the
% pdfetex engine. This is nice because it gives users access to various
% advanced typesetting features. But it's problematic because user
% documents have used, ever since the inception of pdftex, the test
% \ifx\pdfoutput\undefined
% to determine whether they are generating pdf or dvi, whether to use
% the [pdftex] option to graphicx and hyperref, etc.
%
% Also, some packages (geometry) test \pdfpageheight and the like,
% similarly.
%
% Although the generic ifpdf.sty style file tests this more robustly, it
% is asking a lot for everyone to switch.
%
% So this file, read at format-creation time, is our attempt at making
% the change compatible: we *un*define various pdf-related primitives,
% so that tests like the above will continue to work. At the same time,
% we make the undefined primitives available as \normalPRIMITIVE, so
% anyone who really needs to can still get them, despite everything.
