-The preview.sty style file
-==========================
-
-Purpose
--------
-
-The main purpose of the preview package is the extraction of selected
-elements from a LaTeX source, like formulas or graphics, into separate
-pages of a DVI file. A flexible and convenient interface allows it to
-specify what commands and constructs should be extracted. This works
-with DVI files postprocessed by either Dvips and Ghostscript or
-dvipng, but it also works when you are using PDFTeX for generating PDF
-files.
-
-Current uses of the package include the preview-latex package for
-WYSIWYG functionality in the AUCTeX editing environment, generation of
-previews in LyX, as part of the operation of the ps4pdf and pst-pdf
-packages, the tbook XML system and some other tools.
-
-Availability
-------------
-
-The preview package is being developed along and distributed with
-AUCTeX. It can therefore be obtained as part of AUCTeX distribution
-files available at <URL:https://ftp.gnu.org/pub/gnu/auctex/> or its
-mirror at <CTAN:support/auctex>. CTAN also provides a standalone
-version at <CTAN:macros/latex/contrib/preview>. The project page at
-<URL:https://savannah.gnu.org/projects/auctex/> offers downloads and
-anonymous CVS access for cutting edge versions. For more information
-about the preview package please refer to the home page of AUCTeX at
-<URL:https://www.gnu.org/software/auctex/>.
-
-Installation
-------------
-
-To install the preview style file on its own without the entire AUCTeX
-package, run
-tex preview.ins
-If preview.ins happens to be missing, you can regenerate it by running
-tex docstrip
-on preview.dtx with the option `installer'.
-
-Running TeX on preview.ins will then extract further files:
-preview.drv which you can run through LaTeX in order to get the
-documentation for preview.sty, preview.sty itself, a bunch of option
-files with extension .def and a few configuration files with extension
-.cfg. In case your docstrip configuration has not already taken care
-of that, install the files with extension .sty, .def and .cfg to a
-location where LaTeX will be able to find them, generate the
-documentation and have fun.
-
-The license of the original file is the GPL which you'll find a copy
-of in the complete AUCTeX distribution. The distribution will also
-unpack and install the respective LaTeX files with an
-autoconf-supported mechanism, so you might consider using that.
-
-Bug reporting
--------------
-
-Please report problems to <URL:mailto:bug-auctex@gnu.org>, including a
-small example file which uses the \listfiles statement, and the
-resulting log file.

-% \title{The \texttt{preview} Package for \LaTeX\\Version \fileversion}
-% \maketitle
-% \section{Introduction}
-% The main purpose of this package is the extraction of certain
-% environments (most notably displayed formulas) from \LaTeX\ sources
-% as graphics. This works with DVI files postprocessed by either
-% Dvips and Ghostscript or dvipng, but it also works when you are
-% using PDF\TeX\ for generating PDF files (usually also postprocessed
-% by Ghostscript).
-%
-% Current uses of the package include the \previewlatex\ package for
-% WYSIWYG functionality in the AUC\TeX\ editing environment,
-% generation of previews in LyX, as part of the operation of the
-% pst-pdf package, the tbook XML system and some other tools.
-%
-% Producing EPS files with Dvips and its derivatives using the
-% \texttt{-E} option is not a good alternative: People make do by
-% fiddling around with |\thispagestyle{empty}| and hoping for the best
-% (namely, that the specified contents will indeed fit on single
-% pages), and then trying to guess the baseline of the resulting code
-% and stuff, but this is at best dissatisfactory. The preview package
-% provides an easy way to ensure that exactly one page per request
-% gets shipped, with a well-defined baseline and no page decorations.
-% While you still can use the preview package with the `classic'
-% \begin{quote}
-% |dvips -E -i|
-% \end{quote}
-% invocation, there are better ways available that don't rely on Dvips
-% not getting confused by PostScript specials.
-%
-% For most applications, you'll want to make use of the |tightpage|
-% option. This will embed the page dimensions into the PostScript or
-% PDF code, obliterating the need to use the |-E -i| options to Dvips.
-% You can then produce all image files with a single run of
-% Ghostscript from a single PDF or PostScript (as opposed to EPS)
-% file.
-%
-% Various options exist that will pass \TeX\ dimensions and other
-% information about the respective shipped out material (including
-% descender size) into the log file, where external applications might
-% make use of it.
-%
-% The possibility for generating a whole set of graphics with a single
-% run of Ghostscript (whether from \LaTeX\ or PDF\LaTeX) increases
-% both speed and robustness of applications. It is also feasible to
-% use dvipng on a DVI file with the options
-% \begin{quote}
-% |-picky -noghostscript|
-% \end{quote}
-% to omit generating any image file that requires Ghostscript, then
-% let a script generate all missing files using Dvips/Ghostscript.
-% This will usually speed up the process significantly.
-%
-% \section{Package options}
-% The package is included with the customary
-% \begin{quote}
-% |\usepackage|\oarg{options}|{preview}|
-% \end{quote}
-% You should usually load this package as the last one, since it
-% redefines several things that other packages may also provide.
-%
-% The following options are available:
-% \begin{description}
-% \item[|active|] is the most essential option. If this option is not
-% specified, the |preview| package will be inactive and the document
-% will be typeset as if the |preview| package were not loaded,
-% except that all declarations and environments defined by the
-% package are still legal but have no effect. This allows defining
-% previewing characteristics in your document, and only activating
-% them by calling \LaTeX\ as
-% \begin{quote}
-% \raggedright
-% |latex '\PassOptionsToPackage{active}{preview}| |\input|\marg{filename}|'|
-% \end{quote}
-% \item[|noconfig|] Usually the file |prdefault.cfg| gets loaded
-% whenever the |preview| package gets activated. |prdefault.cfg| is
-% supposed to contain definitions that can cater for otherwise bad
-% results, for example, if a certain document class would otherwise
-% lead to trouble. It also can be used to override any settings
-% made in this package, since it is loaded at the very end of it.
-% In addition, there may be configuration files specific for certain
-% |preview| options like |auctex| which have more immediate needs.
-% The |noconfig| option suppresses loading of those option files,
-% too.
-% \item[|psfixbb|] Dvips determines the bounding boxes from the
-% material in the DVI file it understands. Lots of PostScript
-% specials are not part of that. Since the \TeX\ boxes do not make
-% it into the DVI file, but merely characters, rules and specials
-% do, Dvips might include far too small areas. The option |psfixbb|
-% will include |/dev/null| as a graphic file in the ultimate upper
-% left and lower right corner of the previewed box. This will make
-% Dvips generate an appropriate bounding box.
-% \item[|dvips|] If this option is specified as a class option or to
-% other packages, several packages pass things like page size
-% information to Dvips, or cause crop marks or draft messages
-% written on pages. This seriously hampers the usability of
-% previews. If this option is specified, the changes will be undone
-% if possible.
-% \item[|pdftex|] If this option is set, PDF\TeX\ is assumed as the
-% output driver. This mainly affects the |tightpage| option.
-% \item[|xetex|] If this option is set, Xe\TeX\ is assumed as the
-% output driver. This mainly affects the |tightpage| option.
-% \item[|displaymath|] will make all displayed math environments
-% subject to preview processing. This will typically be the most
-% desired option.
-% \item[|floats|] will make all float objects subject to preview
-% processing. If you want to be more selective about what floats to
-% pass through to a preview, you should instead use the
-% \cmd{\PreviewSnarfEnvironment} command on the floats you want to
-% have previewed.
-% \item[|textmath|] will make all text math subject to previews.
-% Since math mode is used throughly inside of \LaTeX\ even for other
-% purposes, this works by redefining \cmd\(, \cmd\)
-% and |$| and the |math| environment (apparently some people use ^^A$
-% that). Only occurences of these text math delimiters in later
-% loaded packages and in the main document will thus be affected.
-% \item[|graphics|] will subject all \cmd{\includegraphics} commands
-% to a preview.
-% \item[|sections|] will subject all section headers to a preview.
-% \item[|delayed|] will delay all activations and redefinitions the
-% |preview| package makes until |\||begin{document}|. The purpose
-% of this is to cater for documents which should be subjected to the
-% |preview| package without having been prepared for it. You can
-% process such documents with
-% \begin{quote}
-% |latex '\RequirePackage[active,delayed,|\meta{options}|]{preview}|
-% |\input|\marg{filename}|'|
-% \end{quote}
-% This relaxes the requirement to be loading the |preview| package
-% as last package.
-% \item[\meta{driver}] loads a special driver file
-% |pr|\meta{driver}|.def|. The remaining options are implemented
-% through the use of driver files.
-% \item[|auctex|] This driver will produce fake error messages at the
-% start and end of every preview environment that enable the Emacs
-% package \previewlatex\ in connection with AUC\TeX\ to pinpoint
-% the exact source location where the previews have originated.
-% Unfortunately, there is no other reliable means of passing the
-% current \TeX\ input position \emph{in} a line to external
-% programs. In order to make the parsing more robust, this option
-% also switches off quite a few diagnostics that could be
-% misinterpreted.
-%
-% You should not specify this option manually, since it will only be
-% needed by automated runs that want to parse the pseudo error
-% messages. Those runs will then use \cmd{\PassOptionsToPackage} in
-% order to effect the desired behaviour. In addition,
-% |prauctex.cfg| will get loaded unless inhibited by the |noconfig|
-% option. This caters for the most frequently encountered
-% problematic commands.
-% \item[|showlabels|] During the editing process, some people like to
-% see the label names in their equations, figures and the like. Now
-% if you are using Emacs for editing, and in particular
-% \previewlatex, I'd strongly recommend that you check out the
-% Ref\TeX\ package which pretty much obliterates the need for this
-% kind of functionality. If you still want it, standard \LaTeX\
-% provides it with the |showkeys| package, and there is also the
-% less encompassing |showlabels| package. Unfortunately, since
-% those go to some pain not to change the page layout and spacing,
-% they also don't change |preview|'s idea of the \TeX\ dimensions of
-% the involved boxes. So if you are using |preview| for determing
-% bounding boxes, those packages are mostly useless. The option
-% |showlabels| offers a substitute for them.
-% \item[|tightpage|] It is not uncommon to want to use the results of
-% |preview| as graphic images for some other application. One
-% possibility is to generate a flurry of EPS files with
-% \begin{quote}
-% |dvips -E -i -Pwww -o| \meta{outputfile}|.000| \meta{inputfile}
-% \end{quote}
-% However, in case those are to be processed further into graphic
-% image files by Ghostscript, this process is inefficient since all
-% of those files need to be processed one by one. In addition, it
-% is necessary to extract the bounding box comments from the EPS
-% files and convert them into page dimension parameters for
-% Ghostscript in order to avoid full-page graphics. This is not
-% even possible if you wanted to use Ghostscript in a~\emph{single}
-% run for generating the files from a single PostScript file, since
-% Dvips will in that case leave no bounding box information
-% anywhere.
-%
-% The solution is to use the |tightpage| option. That way a single
-% command line like
-% \begin{quote}
-% \raggedright
-% \texttt{gs -sDEVICE=png16m -dTextAlphaBits=4 -r300
-% -dGraphicsAlphaBits=4 -dSAFER -q -dNOPAUSE
-% -sOutputFile=\meta{outputfile}\%d.png \meta{inputfile}.ps}
-% \end{quote}
-% will be able to produce tight graphics from a single PostScript
-% file generated with Dvips \emph{without} use of the options
-% |-E -i|, in a single run.
-%
-% The |tightpage| option actually also works when using the |pdftex|
-% option and generating PDF files with PDF\TeX. The resulting PDF
-% file has separate page dimensions for every page and can directly
-% be converted with one run of Ghostscript into image files.
-%
-% If neither |dvips| or |pdftex| have been specified, the
-% corresponding option will get autodetected and invoked.
-%
-% If you need this in a batch environment where you don't want to
-% use |preview|'s automatic extraction facilities, no problem: just
-% don't use any of the extraction options, and wrap everything to be
-% previewed into |preview| environments. This is how LyX does its
-% math previews.
-%
-% If the pages under the |tightpage| option are just too tight, you
-% can adjust by setting the length |\PreviewBorder| to a different
-% value by using \cmd{\setlength}. The default value is
-% |0.50001bp|, which is half of a usual PostScript point, rounded
-% up. If you go below this value, the resulting page size may drop
-% below |1bp|, and Ghostscript does not seem to like that. If you
-% need finer control, you can adjust the bounding box dimensions
-% individually by changing the macro |\PreviewBbAdjust| with the
-% help of |\renewcommand|. Its default value is
-% \begin{quote}
-% \raggedright
-% |\newcommand| |\PreviewBbAdjust|
-% |{-\PreviewBorder| |-\PreviewBorder|
-% |\PreviewBorder| |\PreviewBorder}|
-% \end{quote}
-% This adjusts the left, lower, right and upper borders by the given
-% amount. The macro must contain 4~\TeX\ dimensions after another,
-% and you may not omit the units if you specify them explicitly
-% instead of by register. PostScript points have the unit~|bp|.
-% \item[|lyx|] This option is for the sake of LyX developers. It will
-% output a few diagnostics relevant for the sake of LyX' preview
-% functionality (at the time of writing, mostly implemented for math
-% insets, in versions of LyX starting with 1.3.0).
-% \item[|counters|] This writes out diagnostics at the start and the
-% end of previews. Only the counters changed since the last output
-% get written, and if no counters changed, nothing gets written at
-% all. The list consists of counter name and value, both enclosed
-% in |{}| braces, followed by a space. The last such pair is
-% followed by a colon (|:|) if it is at the start of the preview
-% snippet, and by a period (|.|) if it is at the end. The order of
-% different diagnostics like this being issued depends on the order
-% of the specification of the options when calling the package.
-%
-% Systems like \previewlatex\ use this for keeping counters accurate
-% when single previews are regenerated.
-% \item[|footnotes|] This makes footnotes render as previews, and only
-% as their footnote symbol. A convenient editing feature inside of
-% Emacs.
-% \end{description}
-% The following options are just for debugging purposes of the package
-% and similar to the corresponding \TeX\ commands they allude to:
-% \begin{description}
-% \item[|tracingall|] causes lots of diagnostic output to appear in
-% the log file during the preview collecting phases of \TeX's
-% operation. In contrast to the similarly named \TeX\ command, it
-% will not switch to |\errorstopmode|, nor will it change the
-% setting of |\tracingonline|.
-% \item[|showbox|] This option will show the contents of the boxes
-% shipped out to the DVI files. It also sets |\showboxbreadth| and
-% |\showboxdepth| to their maximum values at the end of loading this
-% package, but you may reset them if you don't like that.
-% \end{description}
-% \section{Provided Commands}
-% \DescribeEnv{preview} The |preview| environment causes its contents
-% to be set as a single preview image. Insertions like figures and
-% footnotes (except those included in minipages) will typically lead
-% to error messages or be lost. In case the |preview| package has not
-% been activated, the contents of this environment will be typeset
-% normally.
-%
-% \DescribeEnv{nopreview} The |nopreview| environment will cause its
-% contents not to undergo any special treatment by the |preview|
-% package. When |preview| is active, the contents will be discarded
-% like all main text that does not trigger the |preview| hooks. When
-% |preview| is not active, the contents will be typeset just like the
-% main text.
-%
-% Note that both of these environments typeset things as usual when
-% preview is not active. If you need something typeset conditionally,
-% use the \cmd{\ifPreview} conditional for it.
-%
-% \DescribeMacro{\PreviewMacro} If you want to make a macro like
-% \cmd{\includegraphics} (actually, this is what is done by the
-% |graphics| option to |preview|) produce a preview image, you put a
-% declaration like
-% \begin{quote}
-% |\PreviewMacro[*[[!]{\includegraphics}|
-% \end{quote}
-% or, more readable,
-% \begin{quote}
-% |\PreviewMacro[{*[][]{}}]{\includegraphics}|
-% \end{quote}
-% into your preamble. The optional argument to \cmd{\PreviewMacro}
-% specifies the arguments \cmd{\includegraphics} accepts, since this
-% is necessary information for properly ending the preview box. Note
-% that if you are using the more readable form, you have to enclose
-% the argument in a |[{| and |}]| pair. The inner braces are
-% necessary to stop any included |[]| pairs from prematurely ending
-% the optional argument, and to make a single |{}|
-% denoting an optional argument not get stripped away by \TeX's
-% argument parsing.
-%
-% The letters simply mean
-% \begin{description}
-% \item[|*|] indicates an optional |*| modifier, as in
-% |\includegraphics*|.
-% \item[|[|]^^A]
-% indicates an optional argument in brackets. This syntax
-% is somewhat baroque, but brief.
-% \item[{|[]|}] also indicates an optional argument in brackets. Be
-% sure to have encluded the entire optional argument specification
-% in an additional pair of braces as described above.
-% \item[|!|] indicates a mandatory argument.
-% \item[|\char`{\char`}|] indicates the same. Again, be sure to have
-% that additional level of braces around the whole argument
-% specification.
-% \item[|?|\meta{delimiter}\marg{true case}\marg{false case}] is a
-% conditional. The next character is checked against being equal to
-% \meta{delimiter}. If it is, the specification \meta{true case} is
-% used for the further parsing, otherwise \meta{false case} will be
-% employed. In neither case is something consumed from the input,
-% so \marg{true case} will still have to deal with the upcoming
-% delimiter.
-% \item[|@|\marg{literal sequence}] will insert the given sequence
-% literally into the executed call of the command.
-% \item[|-|] will just drop the next token. It will probably be most
-% often used in the true branch of a |?| specification.
-% \item[|\#|\marg{argument}\marg{replacement}] is a transformation
-% rule that calls a macro with the given argument and replacement
-% text on the rest of the argument list. The replacement is used in
-% the executed call of the command. This can be used for parsing
-% arbitrary constructs. For example, the |[]| option could manually
-% be implemented with the option string |?[{#{[#1]}{[{#1}]}}{}|.
-% PStricks users might enjoy this sort of flexibility.
-% \item[|:|\marg{argument}\marg{replacement}] is again a
-% transformation rule. As opposed to |#|, however, the result of
-% the transformation is parsed again. You'll rarely need this.
-% \end{description}
-%
-% There is a second optional argument in brackets that can be used to
-% declare any default action to be taken instead. This is mostly for
-% the sake of macros that influence numbering: you would want to keep
-% their effects in that respect. The default action should use |#1|
-% for referring to the original (not the patched) command with the
-% parsed options appended. Not specifying a second optional argument
-% here is equivalent to specifying~|[#1]|.
-%
-% \DescribeMacro{\PreviewMacro*} A similar invocation
-% \cmd{\PreviewMacro*} simply throws the macro and all of its
-% arguments declared in the manner above away. This is mostly useful
-% for having things like \cmd{\footnote} not do their magic on their
-% arguments. More often than not, you don't want to declare any
-% arguments to scan to \cmd{\PreviewMacro*} since you would want the
-% remaining arguments to be treated as usual text and typeset in that
-% manner instead of being thrown away. An exception might be, say,
-% sort keys for \cmd{\cite}.

-% A second optional argument in brackets can be used to declare any

-% that influence numbering: you would want to keep their effects in

-% the original (not the patched) command with the parsed options

-% equivalent to specifying~|[]| since the command usually gets thrown
-% away.
-%
-% As an example for using this argument, you might want to specify
-% \begin{quote}
-% |\PreviewMacro*[{[]}][#1{}]{\footnote}|
-% \end{quote}
-% This will replace a footnote by an empty footnote, but taking any
-% optional parameter into account, since an optional paramter changes
-% the numbering scheme. That way the real argument for the footnote
-% remains for processing by \previewlatex.
-%
-% \DescribeMacro{\PreviewEnvironment} The macro
-% \cmd{\PreviewEnvironment} works just as \cmd{\PreviewMacro} does,
-% only for environments. \DescribeMacro{\PreviewEnvironment*} And the
-% same goes for \cmd{\PreviewEnvironment*} as compared to
-% \cmd{\PreviewMacro*}.
-%
-% \DescribeMacro{\PreviewSnarfEnvironment} This macro does not typeset
-% the original environment inside of a preview box, but instead
-% typesets just the contents of the original environment inside of the
-% preview box, leaving nothing for the original environment. This has
-% to be used for figures, for example, since they would
-% \begin{enumerate}
-% \item produce insertion material that cannot be extracted to the
-% preview properly,
-% \item complain with an error message about not being in outer par
-% mode.
-% \end{enumerate}
-%
-% \DescribeMacro{\PreviewOpen}
-% \DescribeMacro{\PreviewClose}
-% Those Macros form a matched preview pair. This is for macros that
-% behave similar as \cmd{\begin} and \cmd{\end} of an environment. It
-% is essential for the operation of \cmd{\PreviewOpen} that the macro
-% treated with it will open an additional group even when the preview
-% falls inside of another preview or inside of a |nopreview|
-% environment. Similarly, the macro treated with \cmd{\PreviewClose}
-% will close an environment even when inactive.
-%
-% \DescribeMacro{\ifPreview} In case you need to know whether
-% |preview| is active, you can use the conditional \cmd{\ifPreview}
-% together with |\else| and |\fi|.

-% \section{The option files}
-% \subsection{The \texttt{auctex} option}
-% The AUC\TeX\ option will cause error messages to spew. We want them
-% on the terminal, but we don't want \LaTeX\ to stop its automated
-% run. We delay \cmd{\nonstopmode} in case the user has any
-% pseudo-interactive folderol like reading in of file names in his
-% preamble. Because we are so good-hearted, we will not break this as
-% long as the document has not started, but after that we need the
-% error message mechanism operative.
-%
-% The |\nofiles| command here tries to avoid clobbering input files
-% used for references and similar. It will come too late if you call
-% the package with \cmd{\AtBeginDocument}, so you'll need to issue
-% |\nofiles| yourself in that case. Previously, this was done
-% unconditionally in the main style file, but since we don't know what
-% the package may be used for, this was inappropriate.
-%
-% So here is the contents of the |prauctex.def| file:
-% \begin{macrocode}
-%<auctex>\ifPreview\else\expandafter\endinput\fi
-%<auctex>\nofiles
-%<auctex>\preview@delay{\nonstopmode}
-% \end{macrocode}
-% Ok, here comes creative error message formatting. It turns out a
-% sizable portion of the runtime is spent in I/O. Making the error
-% messages short is an advantage. It is not possible to convince
-% \TeX\ to make shorter error messages than this: \TeX\ always wants
-% to include context. This is about the shortest \ae sthetic one we
-% can muster.

-%
-% Since over/underfull boxes are about the messiest things to parse,

-% This outputs a checkpoint. We do this by saving all counter
-% registers in backup macros starting with |\pr@c@| in their name. A
-% checkpoint first writes out all changed counters (previously
-% unchecked counters are not written out unless different from zero),
-% then saves all involved counter values. \LaTeX\ tracks its counters
-% in the global variable \cmd{\cl@ckpt}.
-% \begin{macrocode}
-%<counters>\ifPreview\else\expandafter\endinput\fi
-%<counters>\def\pr@eltprint#1{\expandafter\@gobble\ifnum\value{#1}=0%
-%<counters> \csname pr@c@#1\endcsname\else\relax
-%<counters> \space{#1}{\arabic{#1}}\fi}
-%<counters>\def\pr@eltdef#1{\expandafter\xdef
-%<counters> \csname pr@c@#1\endcsname{\arabic{#1}}}

-%
-% \subsection{Debugging options}
-% Those are for debugging the operation of |preview|, and thus are
-% mostly of interest for people that want to use |preview| for their
-% own purposes. Since debugging output is potentially confusing to
-% the error message parsing from AUC\TeX, you should not turn on
-% |\tracingonline| or switch from |\nonstopmode| unless you are
-% certain your package will never be used with \previewlatex.
-%
-% \paragraph{The \texttt{showbox} option} will generate diagnostic
-% output for every produced box. It does not delay the resetting of
-% the |\showboxbreadth| and |\showboxdepth| parameters so that you can
-% still change them after the loading of the package. It does,
-% however, move them to the end of the package loading, so that they
-% will not be affected by the |auctex| option.
-% \begin{macrocode}
-%<showbox>\ifPreview\else\expandafter\endinput\fi
-%<showbox>\AtEndOfPackage{%
-%<showbox> \showboxbreadth\maxdimen
-%<showbox> \showboxdepth\maxdimen}
-%<showbox>\g@addto@macro\pr@ship@end{\showbox\pr@box}
-% \end{macrocode}
-%
-% \paragraph{The \texttt{tracingall} option} is for the really heavy
-% diagnostic stuff. For the reasons mentioned above, we do not want
-% to change the setting of the interaction mode, nor of the
-% |tracingonline| flag. If the user wants them different, he should
-% set them outside of the preview boxes.
-% \begin{macrocode}
-%<tracingall>\ifPreview\else\expandafter\endinput\fi
-%<tracingall>\pr@addto@front\pr@ship@start{\let\tracingonline\count@
-%<tracingall> \let\errorstopmode\@empty\tracingall}
-% \end{macrocode}
-%
-% \subsection{Supporting conversions}
-% It is not uncommon to want to use the results of |preview| as
-% images. One possibility is to generate a flurry of EPS files with
-% \begin{quote}
-% |dvips -E -i -Ppdf -o| \meta{outputfile}|.000| \meta{inputfile}
-% \end{quote}
-% However, in case those are to be processed further into graphic
-% image files by Ghostscript, this process is inefficient. One cannot
-% use Ghostscript in a single run for generating the files, however,
-% since one needs to set the page size (or full size pages will be
-% produced). The |tightpage| option will set the page dimensions at
-% the start of each PostScript page so that the output will be sized
-% appropriately. That way, a single pass of Dvips followed by a
-% single pass of Ghostscript will be sufficient for generating all
-% images.
-%
-% You will have to specify the output driver to be used, either
-% |dvips| or |pdftex|.
-%
-% \begin{macro}{\PreviewBorder}
-% \begin{macro}{\PreviewBbAdjust}
-% We start this off with the user tunable parameters which get
-% defined even in the case of an inactive package, so that
-% redefinitions and assignments to them will always work:
-% \begin{macrocode}
-%<tightpage>\ifx\PreviewBorder\@undefined
-%<tightpage> \newdimen\PreviewBorder
-%<tightpage> \PreviewBorder=0.50001bp
-%<tightpage>\fi
-%<tightpage>\ifx\PreviewBbAdjust\@undefined
-%<tightpage> \def\PreviewBbAdjust{-\PreviewBorder -\PreviewBorder
-%<tightpage> \PreviewBorder \PreviewBorder}
-%<tightpage>\fi
-% \end{macrocode}
-% \end{macro}
-% \end{macro}
-% Here is stuff used for parsing this:
-% \begin{macrocode}
-%<tightpage>\ifPreview\else\expandafter\endinput\fi
-%<tightpage>\def\pr@nextbb{\edef\next{\next\space\number\dimen@}%
-%<tightpage> \expandafter\xdef\csname pr@bb@%
-%<tightpage> \romannumeral\count@\endcsname{\the\dimen@}%
-%<tightpage> \advance\count@\@ne\ifnum\count@<5
-%<tightpage> \afterassignment\pr@nextbb\dimen@=\fi}
-% \end{macrocode}
-% And here is the stuff that we fudge into our hook. Of course, we
-% have to do it in a box, and we start this box off with our special.
-% There is one small consideration here: it might come before any
-% |\AtBeginDvi| stuff containing header specials. It turns out Dvips
-% rearranges this amicably: header code specials get transferred to
-% the appropriate header section, anyhow, so this ensures that we come
-% right after the bop section. We insert the 7~numbers here: the
-% 4~bounding box adjustments, and the 3~\TeX\ box dimensions. In case
-% the box adjustments have changed since the last time, we write them
-% out to the console.

-% Ok, here comes the beef. First we fish the 7~numbers from the file

-% Backwards-compatibility. Once we are certain that dvipng-1.6 or

-% \begin{macrocode}

-%<tightpage> {0 ge{neg}if exch}forall]>>setpagedevice%
-%<tightpage> //bop-hook exec}bind def end}
-%<tightpage> \special{!userdict (some extra code to avoid
-%<tightpage> dvipng>=1.6 unknown special:
-%<tightpage> 7{currentfile token not{stop}if 65781.76 div })) pop}
-% \end{macrocode}
-% The ``userdict'' at the start of the last special is also there to
-% avoid an unknown special in dvipng$<=1.6$. This is the end of the
-% backwards-compatibility code.
-% \begin{macrocode}
-%<tightpage> \special{!userdict begin/bop-hook{%
-%<tightpage> preview-bop-level 0 le{%
-%<tightpage> 7{currentfile token not{stop}if
-%<tightpage> 65781.76 div DVImag mul}repeat
-% \end{macrocode}
-% Next we produce the horizontal part of the bounding box as
-% \[ (1\mathrm{in},1\mathrm{in}) +
-% \bigl(\min(|\wd\pr@box|,0),\max(|\wd\pr@box|,0)\bigr) \]
-% and roll it to the bottom of the stack:
-% \begin{macrocode}
-%<tightpage> 72 add 72 2 copy gt{exch}if 4 2 roll
-% \end{macrocode}
-% Next is the vertical part of the bounding box. Depth counts in
-% negatively, and we again take $\min$ and $\max$ of possible extents
-% in the vertical direction, limited by 0. 720 corresponds to
-% $10\,\mathrm{in}$ and is the famous $1\,\mathrm{in}$ distance away
-% from the edge of letterpaper.
-% \begin{macrocode}
-%<tightpage> neg 2 copy lt{exch}if dup 0 gt{pop 0 exch}%
-%<tightpage> {exch dup 0 lt{pop 0}if}ifelse 720 add exch 720 add
-%<tightpage> 3 1 roll
-% \end{macrocode}
-% Ok, we now have the bounding box on the stack in the proper order
-% llx, lly, urx, ury. We add the adjustments:

-% \end{macrocode}
-% The page size is calculated as the appropriate differences, the page

-% So we now bind the old definition of |bop-hook| into our new

-%<tightpage>\fi
-% \end{macrocode}
-%
-% \subsection{The \texttt{showlabels} option}
-% During the editing process, some people like to see the label names
-% in their equations, figures and the like. Now if you are using
-% Emacs for editing, and in particular \previewlatex, I'd strongly
-% recommend that you check out the Ref\TeX\ package which pretty much
-% obliterates the need for this kind of functionality. If you still
-% want it, standard \LaTeX\ provides it with the |showkeys| package,
-% and there is also the less encompassing |showlabels| package.
-% Unfortunately, since those go to some pain not to change the page
-% layout and spacing, they also don't change |preview|'s idea of the
-% \TeX\ dimensions of the involved boxes.
-%
-% So those packages are mostly useless. So we present here an
-% alternative hack that will get the labels through.
-% \begin{macro}{\pr@labelbox}
-% This works by collecting them into a separate box which we then
-% tack to the right of the previews.
-% \begin{macrocode}
-%<showlabels>\ifPreview\else\expandafter\endinput\fi
-%<showlabels>\newbox\pr@labelbox
-% \end{macrocode}
-% \end{macro}
-% \begin{macro}{\pr@label}
-% We follow up with our own definition of the \cmd{\label} macro
-% which will be active only in previews. The original definition is
-% stored in |\pr@@label|. |\pr@lastlabel| contains the last typeset
-% label in order to avoid duplication in certain environments, and
-% we keep the stuff in |\pr@labelbox|.
-% \begin{macrocode}
-%<showlabels>\def\pr@label#1{\pr@@label{#1}%
-% \end{macrocode}
-% Ok, now we generate the box, by placing the label below any existing
-% stuff.
-% \begin{macrocode}
-%<showlabels> \ifpr@setbox\z@{#1}%
-%<showlabels> \global\setbox\pr@labelbox\vbox{\unvbox\pr@labelbox
-%<showlabels> \box\z@}\egroup\fi}
-% \end{macrocode}
-% \end{macro}
-% \begin{macro}{\ifpr@setbox}
-% |\ifpr@setbox| receives two arguments, |#1| is the box into which
-% to set a label, |#2| is the label text itself. If a label needs
-% to be set (if it is not a duplicate in the current box, and is
-% nonempty, and we are in the course of typesetting and so on), we
-% are left in a true conditional and an open group with the preset
-% box. If nothing should be set, no group is opened, and we get
-% into skipping to the closing of the conditional. Since
-% |\ifpr@setbox| is a macro, you should not place the call to it
-% into conditional text, since it will not pair up with |\fi| until
-% being expanded.
-%
-% We have some trickery involved here. |\romannumeral\z@| expands
-% to empty, and will also remove everything between the two of them
-% that also expands to empty, like a chain of |\fi|.
-% \begin{macrocode}
-%<showlabels>\def\ifpr@setbox#1#2{%
-%<showlabels> \romannumeral%
-%<showlabels> \ifx\protect\@typeset@protect\ifpr@outer\else
-% \end{macrocode}
-% Ignore empty labels\dots
-% \begin{macrocode}
-%<showlabels> \z@\bgroup
-%<showlabels> \protected@edef\next{#2}\@onelevel@sanitize\next
-%<showlabels> \ifx\next\@empty\egroup\romannumeral\else
-% \end{macrocode}
-% and labels equal to the last one.
-% \begin{macrocode}
-%<showlabels> \ifx\next\pr@lastlabel\egroup\romannumeral\else
-%<showlabels> \global\let\pr@lastlabel\next
-%<showlabels> \setbox#1\pr@boxlabel\pr@lastlabel
-%<showlabels> \expandafter\expandafter\romannumeral\fi\fi\fi\fi
-%<showlabels> \z@\iffalse\iftrue\fi}
-% \end{macrocode}
-% \end{macro}
-% \begin{macro}{\pr@boxlabel}
-% Now the actual typesetting of a label box is done. We use a small
-% typewriter font inside of a framed box (the default frame/box
-% separating distance is a bit large).
-% \begin{macrocode}
-%<showlabels>\def\pr@boxlabel#1{\hbox{\normalfont
-%<showlabels> \footnotesize\ttfamily\fboxsep0.4ex\relax\fbox{#1}}}
-% \end{macrocode}
-% \end{macro}
-% \begin{macro}{\pr@maketag}
-% And here is a version for |amsmath| equations. They look better
-% when the label is right beside the tag, so we place it there, but
-% augment |\box\pr@labelbox| with an appropriate placeholder.
-% \begin{macrocode}
-%<showlabels>\def\pr@maketag#1{\pr@@maketag{#1}%
-%<showlabels> \ifpr@setbox\z@{\df@label}%
-%<showlabels> \global\setbox\pr@labelbox\vbox{%
-%<showlabels> \hrule\@width\wd\z@\@height\z@
-%<showlabels> \unvbox\pr@labelbox}%
-% \end{macrocode}
-% Set the width of the box to empty so that the label placement gets
-% not disturbed, then append it.
-% \begin{macrocode}
-%<showlabels> \wd\z@\z@\box\z@ \egroup\fi}
-% \end{macrocode}
-% \end{macro}
-% \begin{macro}{\pr@lastlabel}
-% Ok, here is how we activate this: we clear out box and label info
-% \begin{macrocode}
-%<showlabels>\g@addto@macro\pr@ship@start{%
-%<showlabels> \global\setbox\pr@labelbox\box\voidb@x
-%<showlabels> \xdef\pr@lastlabel{}%
-% \end{macrocode}
-% The definitions above are global because we might be in any amount
-% of nesting. We then reassign the appropriate labelling macros:
-% \begin{macrocode}
-%<showlabels> \global\let\pr@@label\label \let\label\pr@label
-%<showlabels> \global\let\pr@@maketag\maketag@@@
-%<showlabels> \let\maketag@@@\pr@maketag
-%<showlabels>}
-% \end{macrocode}
-% \end{macro}
-% Now all we have to do is to add the stuff to the box in question.
-% The stuff at the front works around a bug in |ntheorem.sty|.
-% \begin{macrocode}
-%<showlabels>\pr@addto@front\pr@ship@end{%
-%<showlabels> \ifx \label\pr@label \global\let\label\pr@@label \fi
-%<showlabels> \ifx \maketag@@@\pr@maketag
-%<showlabels> \global\let\maketag@@@\pr@@maketag \fi
-%<showlabels> \ifvoid\pr@labelbox
-%<showlabels> \else \setbox\pr@box\hbox{%
-%<showlabels> \box\pr@box\,\box\pr@labelbox}%
-%<showlabels> \fi}
-% \end{macrocode}
-% \subsection{The \texttt{footnotes} option}
-% This is rather simplistic right now. It overrides the default
-% footnote action (which is to disable footnotes altogether for better
-% visibility).
-% \begin{macrocode}
-%<footnotes>\PreviewMacro[[!]\footnote %]
-% \end{macrocode}
-%
-% \section{Various driver files}
-% The installer, in case it is missing. If it is to be used via
-% |make|, we don't specify an installation path, since
-% \begin{quote}
-% |make install|
-% \end{quote}
-% is supposed to cater for the installation itself.
-% \begin{macrocode}
