+% Including DVI Sections Into The Current File
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+% Graphics will be able to include dvi file segments, reading size
+% info from .dat files (compatible with dvipast.tex for plain tex)
+
+\DeclareGraphicsRule{.dvi}{dvi}{.dat}{}
+
+% Add .dvi to the default list of extensions.
+
+\g@addto@macro\Gin@extensions{,.dvi}
+
+
+% dvipaste allows multiple dvi fragments to be included from the
+% same file. Add a new key num= (defaulting to 1) which says
+% which bit to include. Maintaining numbers if you have a lot of
+% fragments is inconvenient so may use symbolic references
+% instead of number.
+% ref=xxx refers to a fragment marked with the label xxx by use
+% of an optional argument \sendout[xxx]{......} to \sendout.
+% If \sendout is used with such an optional argument
+% the fragment may be included either by number or by label.
+% (The numeric form must be used if the fragment is included using
+% dvipaste.tex's \paste command.)
+
+
+\define@key{Gin}{num}{\def\Gin@num{#1}}
+\define@key{Gin}{ref}{\def\Gin@ref{#1 }}
+\setkeys{Gin}{num=1,ref=}
+
+% Unlike other graphics formats, which only have natural height and
+% width, dvipaste fragments are TeX boxes, with depth as well.
+% add a new key to set the depth (for cases where you don't want to
+% use a .dat file).
+
+\define@key{Gin}{natdepth}{%
+ \Gin@defaultbp\@tempaa{#1}%
+ \Gin@nat@depth\@tempaa bp\relax}
+
+% Ah. Don't look too carefully. The internal command \Gin@setfile
+% in the kernel of the graphics package was not expecting this, and
+% explicitly sets the depth of the graphic box to zero, so patch that
+% to make it set it to the new \Gin@req@depth macro.
+%
+% pulls apart the macro at \dp\z@\z@ and then puts it all back together
+% again.
+
+\def\@tempa#1\dp\z@\z@#2!{%
+ \def\Gin@setfile##1##2##3{%
+ #1%
+ \dp\z@\Gin@req@depth
+ #2}}
+\expandafter\@tempa\Gin@setfile{#1}{#2}{#3}!
+
+% Scaling is not currently supported, so natural depth and
+% required depth are the same.
+
+\def\Gin@req@depth{\Gin@nat@depth}
+
+\newdimen\Gin@nat@depth
+
+
+% For each new file type the graphics package needs two functions.
+% \Gread@<type> defines how to read the size information.
+% \Ginclude@type defines how to set the actual box and specials.
+% These functions are pretty similar to the code in dvipaste.tex
+
+% as in the dvipaste.tex version, the size information for
+% all the fragments in a single dvi file is saved in a macro
+% so the file only needs to be read once.
