%D This driver is build on top of the general \PDF\ macros,
%D as defined in \type{spec-fdf}, so we inherit that one. Remark:
%D this driver is no longer actively maintained, use the dpx one
%D instead!

%D \macros
%D   {jobsuffix}
%D
%D Because no intermediate output format is used, we set the
%D jobsuffix to \PDF.

\def\jobsuffix{pdf}

%D Literal \PDF\ inclusion is implemented as:

\def\PDFcode       #1{\special{pdf: content #1}}
\def\PDFcontentcode#1{\special{pdf: content #1}}
\def\PDFdirectcode #1{\special{pdf: literal #1}}

%D Unfortunately the direct \PDF\ inclusion is not suited
%D for the next macros, which means that we cannot use the
%D \type {\doPDF..} alternatives. Since \CONTEXT\ maintains
%D its own colorstack, we use the \DVIPS\ alternatives.
