+% 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.
