-The chemscheme package --- Support for chemical schemes
-Maintained by Joseph Wright

-The chemscheme package consists of two parts, both related to
-chemical schemes.  The package adds a scheme float type to the
-LaTeX default types figure and table. The scheme float type
-acts in the same way as those defined by the LaTeX kernel, but
-is intended for chemical schemes.  The package also provides a
-method for adding automatic chemical numbering to schemes.

-%\begin{abstract}
-% The |chemscheme| package consists of two parts, both related to
-% chemical schemes.  The package adds a |scheme| float type to the
-% LaTeX default types |figure| and |table|. The |scheme| float type
-% acts in the same way as those defined by the LaTeX kernel,  but is
-% intended for chemical schemes.  The package also provides a method
-% for adding automatic chemical numbering to schemes.

-%\section{Introduction}
-% By default, LaTeX defines two float types, |figure| and |table|.
-% Synthetic chemists make heavy use of schemes, which need a |scheme|
-% float type.  This is provided by |chemscheme|, in a manner
-% consistent with the kernel floats.
-%
-% Synthetic chemists also number compounds for ease of reference.
-% There are a number of LaTeX packages which cover this area, most
-% notably |bpchem| and |chemcompounds|.  However, adding numbers
-% automatically to schemes is not covered by any existing package.
-% The |chemscheme| package seeks to rectify this.
-%\floatcontentscentre
-%
-%\section{Floating schemes}
-%\subsection{Basic use}
-%\DescribeEnv{scheme}
-% The package provides a new float type, scheme, accessed in the
-% usual way.
-%\begin{LaTeXexample}[\typesetfloatexample]
-% \begin{scheme}[ht]
-%   \includegraphics{scheme-one}
-%   \caption{A scheme with no compound numbers.}
-% \end{scheme}
-%\end{LaTeXexample}
-% The |scheme| float is designed to behave in the same way as the
-% standard LaTeX float environments |figure| and |table|.  Thus
-% schemes will be placed at the top of a page, where possible. As
-% shown in the example, the use of positional modifiers is allowed.
-% Labelling and referencing schemes also follows the LaTeX
-% conventions.  |chemscheme| works hard to emulate the document class
-% in use, and so the exact behaviour will depend on whether the
-% standard classes, \textsc{koma-script} or |memoir| are being used.
-%
-% \DescribeMacro{\listofschemes}
-% \DescribeMacro{\listschemename}
-% To match the \cmd{\listoffigures} and \cmd{\listoftables} macros
-% provided by the LaTeX kernel, |chemscheme| provides a
-% \cmd{\listofschemes} command.  This works in the same way as the
-% kernel commands, with the default text stored in the macro
-% \cmd{\listschemename}.  Users upgrading from version 1.1 should
-% note the change of macro name (from \cmd{\listscheme}).  This
-% is to bring |chemscheme| into line with the LaTeX kernel
-% naming convention.  Also notice that \cmd{\listofschemes} no longer
-% accepts an optional argument.  The standard output is illustrated
-% below.
-%\begin{LaTeXexample}[\typesetcodeandexample]
-% \listofschemes
-%\end{LaTeXexample}
-%
-%\subsection{Altering the defaults}
-%
-% For users of the standard class files or the \textsc{koma-script}
-% bundle, the |float| package is used to create the new float type.
-% Thus the usual |float| commands can be used to modify the behaviour
-% as desired. Users of |memoir| will have slightly different commands
-% available, as |memoir| implements its own new float mechanism,
-% which is used in that case.  Anything that you can do for a
-% standard float, you should be able to to do for a scheme, and it
-% should behave in the same way as a figure or a table.  Please
-% let the package maintainer know of any bugs in this support.
-%
-% \DescribeMacro{\schemename}
-% \cmd{\schemename} contains the text used in scheme captions (by
-%  default \schemename).  This is used in the same manner as
-% \cmd{\figurename} or \cmd{\tablename} to set up the text used in
-% scheme captions.
-%\begin{LaTeXexample}[\typesetfloatexample]
-% \renewcommand*{\schemename}{Illustration}
-% \begin{scheme}[ht]
-%   \includegraphics{scheme-one}
-%   \caption{A scheme that is not a Scheme!}
-% \end{scheme}
-%\end{LaTeXexample}
-% ^^A The name is reset to normal after the example
-%\renewcommand*{\schemename}{Scheme}
-%
-%\subsection{\texttt{babel} support}
-% Schemes are provided with some support for |babel|.  Currently, in
-% addition to English, |chemscheme| provides alternatives for
-% \cmd{\schemename} and \cmd{\listschemename} in French and German.
-% Users of other languages are encouraged to supply suitable
-% translations for inclusion in future versions of |chemscheme|.
-%
-%\section{Horizontal positioning of all floats}
-%\DescribeMacro{\floatcontentscentre}
-%\DescribeMacro{\floatcontentscenter}
-%\DescribeMacro{\floatcontentsleft}
-%\DescribeMacro{\floatcontentsright}
-% The LaTeX default is to position all float contents flush-left.
-% There is no ``hook'' provided to alter this.  The |chemscheme|
-% packages therefore provides commands to align all float contents
-% automatically.  As the macro names make clear,
-% \cmd{\floatcontentscentre} will make all floats centred (for users
-% speaking U.S.~English, the alternative spelling
-% \cmd{\floatcontentscenter} is also available).  The default
-% behaviour is restored using the command \cmd{\floatcontentsleft}.
-% Finally, \cmd{\floatcontentsright} is provided  for use if needed.
-% Notice that the float positioning commands should be given
-% \emph{outside} floating environments, and apply to all subsequent
-% floats.
-%\begin{LaTeXexample}[\typesetfloatexample]
-% \floatcontentsleft
-% \begin{scheme}[ht]
-%   \includegraphics{scheme-one}
-%   \caption{A flush-left scheme.}
-% \end{scheme}
-% \floatcontentsright
-% \begin{scheme}[ht]
-%   \includegraphics{scheme-one}
-%   \caption{A flush-right scheme.}
-% \end{scheme}
-% \floatcontentscentre
-%\end{LaTeXexample}
-%
-% It is important to note that the positioning mechanism used here
-% relies on a low-level hack of the LaTeX kernel.  This has been
-% tested with the standard LaTeX classes, the \textsf{memoir} class
-% and the \textsc{koma-script} bundled.  Other document classes may
-% not give the desired behaviour.
-%
-%\section{Reference numbers in graphics}
-%\subsection{Background}
-% There are a number of packages available on \textsc{ctan} for
-% tracking compound reference numbers.  The two with the most up to
-% date and comprehensive features are |bpchem| and |chemcompounds|.
-% Both allow in-text numbering to be handled automatically.  However,
-% neither will allow the use of these numbers directly in schemes,
-% figures, \emph{etc.}  Both leave it to the user to manually
-% adapt schemes to match any changes in numbering.
-%
-% The |chemscheme| package provides a mechanism for rectifying this
-% issue.  The package makes use of the |psfrag| package, which means
-% that it can only directly produce DVI output (using LaTeX).
-% However, direct PDF output using PDFLaTeX is possible: see
-% Section~\ref{subsec:pdf}.
-%
-%\DescribeMacro{\chemschemeref}
-%\DescribeMacro{\chemschemerefsub}
-% Users upgrading from v.2 should note that ``chem'' has been removed
-% from the start of most macro names.  The main referencing commands
-% \cmd{\chemschemeref} and \cmd{\chemschemerefsub} are retained for
-% backward compatibility.
-%
-%\subsection{Usage}
-% Getting automated numbers into schemes is a two step procedure. In
-% the first step, schemes (or other graphics) should be prepared as
-% normal and saved as encapsulated postscript (EPS) files The most
-% popular chemistry drawing package, \textsc{ChemDraw}, is able to do
-% this from the \texttt{Save As \ldots} dialog.
-%\DescribeMacro{\schemerefmarker}
-% The positions where the auto-labels should be have to be marked in
-% the EPS file. The marker should consist of an ``indicator'' that
-% the text is to be replaced, followed by a reference number or
-% letter.  For automated substitution, the ``indicator'' text should
-% be the same in all graphics; the value it is stored in
-% \cmd{\schemerefmarker}, and has default value
-% \textsf{\schemerefmarker}.  Thus the graphics should contain labels
-% \textsf{\schemerefmarker1}, \textsf{\schemerefmarker2}, \emph{etc}.
-% A suitable unmodified graphic is shown in in the next example.
-%\begin{LaTeXexample}[\typesetfloatexample]
-% \begin{scheme}[ht]
-%   \includegraphics{scheme-two}
-%   \caption{A scheme with temporary compound numbers.}
-% \end{scheme}
-%\end{LaTeXexample}
-% The value of \cmd{\schemerefmarker} may be altered as normal,
-% so for example to use \textsf{XXX} as the indicator for
-% replacement in all graphics, you would execute:
-%\begin{LaTeXexample}[\typesetcodeonly]
-% \renewcommand*{\chemeschemerefmarker}{XXX}
-%\end{LaTeXexample}
-%
-%\DescribeMacro{\schemeref}
-% In the second step, the command \cmd{\schemeref} is used to
-% indicate the mapping of the temporary markers to the
-% automatically-managed numbering. The syntax of the command is
-% \cmd{\chemschemeref}\oarg{temp-marker}\marg{label}, where
-% \meta{temp-marker} is the marker used in the graphic, and
-% \meta{label} is the name assigned to the compound by the user. By
-% default, |chemscheme| will assume that \meta{temp-marker} consists
-% of the marker plus a number, beginning at 1 and incrementing by 1
-% for each additional structure inside one float. Each replacement
-% requires a separate \cmd{\chemschemeref}, all of which should
-% appear before the relevant \cmd{\includegraphics} command.
-%
-% An example will make usage clearer. In the example used in this
-% document, the starting material is given label |IMesHCl| and the
-% product is called |IMes|.  As is shown in the next example, in the
-% EPS file these are labelled \textsf{TMP1} and \textsf{TMP2},
-% respectively. The automated package defaults are used.
-%\begin{LaTeXexample}[\typesetfloatexample]
-% \begin{scheme}[ht]
-%   \schemeref{IMesHCl}
-%   \schemeref{IMes}
-%   \includegraphics{scheme-two}
-%   \caption{A scheme with automated compound numbers.}
-% \end{scheme}
-%\end{LaTeXexample}
-% With user-specified information on the text to be replaced, the
-% entire text to be matched must be given.\footnote{In this example,
-% this is redundant as the automated system will work fine.}
-%\begin{LaTeXexample}[\typesetfloatexample]
-% \begin{scheme}[ht]
-%   \schemeref[TMP1]{IMesHCl}
-%   \schemeref[TMP2]{IMes}
-%   \includegraphics{scheme-two}
-%   \caption{A scheme with explicitly numbered temporary labels.}
-% \end{scheme}
-%\end{LaTeXexample}
-% Notice that the new label is centred on the middle of the temporary
-% marker, with the same baseline.  This should allow the user to
-% obtain good alignment of labels and structures.
-%
-%\DescribeMacro{\schemerefsub}
-% As described in Section~\ref{packages}, |chemscheme| supports
-% |bpchem|, which allows tracking of sub-labels (\textbf{1a},
-% \textbf{1b}, \emph{etc.}).  To allow use of these in schemes, the
-% \cmd{\schemerefsub} command is provided.  This takes an additional
-% argument \marg{sub-label}, which is used to generate the
-% appropriate text.  When used with |chemcompounds|, this command
-% will gobble its arguments and issue a warning; no substitution will
-% take place.
-%
-%\DescribeMacro{\schemerefformat}
-% The format of chemical references is controlled by the underlying
-% package, |bpchem| or |chemcompounds|.  However, it is useful to be
-% able to specify additional formatting for schemes.  By default,
-% |chemscheme| formats all reference numbers in a sans serif font.
-% This is controlled by \cmd{\schemerefformat}.
-%\begin{LaTeXexample}[\typesetfloatexample]
-% % This needs the color or xcolor package loaded
-% \renewcommand*{\schemerefformat}
-%   {\color{magenta}\textit}
-% \begin{scheme}[ht]
-%   \schemeref{IMesHCl}
-%   \schemeref{IMes}
-%   \includegraphics{scheme-two}
-%   \caption{A scheme with altered label formatting.}
-% \end{scheme}
-%\end{LaTeXexample}
-% The additional formatting applied within schemes may be altered by
-% redefining \cmd{\schemerefformat}.  By careful choice of the
-% font commands given here, good visual matching should be obtained
-% between the automatically-generated labels and other text in the
-% scheme.  In this document, the \textsc{ChemDraw} source uses 10
-% point Arial, with the LaTeX sans serif font provided by the
-% |helvet| package, loaded scaled to 95\percent, \emph{i.e.}:
-%\begin{LaTeXexample}[\typesetcodeonly]
-% \usepackage[scaled=0.95]{helvet}
-%\end{LaTeXexample}
-% The \textsc{ChemDraw} file used to generate the example schemes
-% is included with the package as |chemscheme.cdx|.
-%
-%\subsection{\texttt{chemscheme} and PDFLaTeX\label{subsec:pdf}}
-% The automatic substitution of numbers in graphics relies on the the
-% |psfrag| package.  This works with \textsc{PostScript} files, and
-% cannot therefore be used with PDFLaTeX.  However, all is not lost
-% as the |pst-pdf| package provides a method for including
-% \textsc{PostScript} files in a PDFLaTeX run.  However, this is not
-% automatic and some effort is needed by the user.\footnote{The rest
-% of this section is based closely on an example by Stefan Pinnow.}
-% The example below shows a example for using PDFLaTeX with
-% |chemscheme|.\footnote{This example is saved as
-% \texttt{example.tex} when this documentation is compiled.}
-% ^^A This example is saved for the user as ``example.tex''
-%\edef\LaTeXexamplefile{example.tex}
-%\begin{LaTeXexample}[\typesetcodeonly]
-% \documentclass{article}
-% \usepackage[T1]{fontenc}
-% \usepackage{graphicx,chemscheme}
-% % Remove inactive after the first LaTeX run
-% \usepackage[inactive,final]{pst-pdf}
-% \begin{document}
-% \floatcontentscentre
-% An example file for PDFLaTeX use.
-% \begin{scheme}
-%   \schemeref{IMesHCl}
-%   \schemeref{IMes}
-%   \includegraphics{scheme-two}
-%   \caption{A scheme with automated compound numbers.}
-%   \label{sc:scheme-one}
-% \end{scheme}
-% \end{document}
-%\end{LaTeXexample}
-%\edef\LaTeXexamplefile{\jobname.tmp}
-%
-% First you need to run the file through LaTeX, so your package can
-% make the replacements in the picture. Then you need another run
-% through LaTeX with the |inactive| option |pst-pdf| removed so that
-% the modified pictures are extracted.\footnote{You can simply do the
-% first LaTeX run without loading \texttt{pst-pdf} at all, if you
-% prefer.}  Do not worry that you end up with a very odd looking DVI!
-% Then you have to convert the extracted pictures to PDF by the
-% following commands
-%\begin{verbatim}
-%  dvips -o \jobname-pics.ps \jobname.dvi
-%  ps2pdf \jobname-pics.ps
-%\end{verbatim}
-% This converts the modified graphics into PDF format. After this,
-% you can use PDFLaTeX as normal for your schemes. Notice that you
-% will have to repeat the process if you need to modify the schemes
-% or numbering in any way.
-%
-%\subsection{Managing chemical numbering\label{packages}}
-% The |chemscheme| package can use one of two packages for management
-% of chemical numbering: |bpchem| and |chemcompounds|. As of v1.3,
-% |chemcompounds| is the default package for managing reference
-% numbers.\footnote{The change from \texttt{bpchem} is due to issues
-% with \texttt{hyperref} support.  The method used by \texttt{bpchem}
-% to generate compound labels means that they are made into
-% hyperlinks by \texttt{hyperref}, and therefore end up coloured when
-% using the \texttt{colorlinks} option.  This is unlikely to be the
-% desired effect, and \texttt{chemcompounds} does not behave in this
-% way.} Both packages have advantages: |bpchem| allows the tracking
-% of sub-references (very common in organic chemistry), whilst
-% |chemcompounds| has a very well thought-out interface.  It is
-% technically feasible to support both simultaneously, but this is
-% unlikely to have wide application. For this reason, |chemscheme|
-% loads only one package (depending on the user option given), and
-% uses this package to provide numbering management. Both |bpchem|
-% and |chemcompounds| provide a variety of methods for defining
-% chemical labels.
-%
-%\section{Generating chemical schemes}
-%
-%\subsection{Overview}
-% There are a number of ways of generating the graphical content of
-% schemes.  The choice of method will depend on what is available to
-% the user, and how complex the schemes desired are. In this section,
-% an overview of several approaches is given.\footnote{Thanks to
-% Norwid-R.\ Behrnd for suggesting this section and giving a number
-% of useful examples and tips.}  The package author, who is a
-% research worker in a university, favours using \textsc{ChemDraw} as
-% it is regarded by many synthetic chemists as the best tool for this
-% job.  However, this is clearly overkill for users requiring a
-% single diagram on a one-off basis. \textsc{ChemDraw} is also a
-% commercial package running only under Windows and the MacOS. The
-% following is necessarily somewhat brief and selective.  For a
-% thorough overview of graphics in LaTeX, see Goossens \emph{et
-% al.}~\cite{Goossens2007}.
-%
-%\subsection{Macro-based methods}
-% At the most basic, a chemical scheme is simply a collection of
-% lines and symbols, as with any vector diagram.  Hence, it is
-% possible to construct schemes directly using packages such as
-% PSTricks or |pgf|/|tikz|.  This is a complex method, and cannot be
-% recommended for anyone except the very experienced and brave.
-%
-% At a more practical level, there are two packages available which
-% allow typesetting of chemical structures in (La)TeX, using
-% specialised commands: XyMTeX and ppchTeX.  Recent versions of the
-% XyMTeX package have not been made available on \textsc{ctan}, and
-% the version held there is therefore considered to be obsolete.  On
-% the other hand, the ppchTeX system, developed originally for
-% ConTeXt, is available. Both systems suffer from the lack of
-% chemical logic in the input: it is very hard to tell from the code
-% what is being represented. Drawing items such as ``curly arrows'',
-% or making subtle alterations to positioning, is very challenging in
-% purely macro-based systems.  For these reasons, it is usually much
-% more sensible to examine the available graphical methods.
-%
-%\subsection{Graphical methods}
-% Moving to graphical systems, there is no reason that
-% general-purpose vector drawing packages cannot be used for schemes.
-% There are obviously several commercial (\textsc{CorelDraw},
-% \textsc{Adobe Illustrator}, \emph{etc.}) and freeware (for example
-% the \textsc{gimp}) drawing packages that can be used in this way.
-% Simply rings and lines can easily be constructed, although in
-% general-purpose programs the user has to watch that all bonds
-% are the same length.
-%
-% For producing a large number of complex schemes, the particular
-% abilities of dedicated software become a necessity. As well as the
-% already-mentioned \textsc{ChemDraw}, programs such as \textsc{ISIS
-% Draw} and \textsc{ChemSketch} are available free for personal
-% use;\footnote{``Free'' as in without charge, not as in open
-% source.} these programs are all Windows specific.  In the
-% open-source arena, there are a number of packages such as
-% \textsc{XDrawChem} and \textsc{BKchem}, which offer cross-platform
-% functionality.  The differences between the various packages are in
-% the ease of use, and ability to generate well-formattd output (for
-% example, aligning structures).
-%
-% One which deserves mention for the TeX user is TpX.  This is a
-% general purpose Windows graphics program specifically aimed at
-% producing TeX-friendly output (such as PSTricks and |tikz| code)
-% from a graphical interface. TpX can accept clipboard data from
-% other programs, so can be used to produce EPS files from programs
-% which do not have native export facilities (such as \textsc{ISIS
-% Draw}).
-%
-%\section{Known issues}
-%
-% The interaction of the different document classes, with options,
-% plus the |babel| system means ensuring every possibility is covered
-% is impossible.  Users are asked to report any problems with
-% compatibility with other packages or emulation of the standard
-% float types.  Additional |babel| stings are also welcome, as are
-% improvements to those already provided.

-% The following is convenient method for collecting together package
-% loading, formatting commands and new macros used to format |dtx|
-% files written by the current author.  It is based on the similar
-% files provided by Will Robertson in his packages and Heiko Oberdiek
-% as a stand-alone package.  Notice that it is not intended for other
-% users: there is no error checking!  However, it is covered by the
-% LPPL in the same way as the rest of this package.
