% 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.
%
% \end{abstract}
%
% \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 |chemescheme| package seeks to rectify this.
%
% \section{Floating schemes}
%
% \subsection{Basic use}
%
% \DescribeEnv{scheme}
% The package provides a new float type, scheme, accessed in the
% usual way.  So, issuing the following commands:
% \begin{scheme}[ht]
%   \centering
%   \includegraphics{scheme-one}\\
%   \caption{A scheme with no compound numbers.}
%   \label{scheme-one}
% \end{scheme}
% \begin{verbatim}
% \begin{scheme}[ht]
%   \centering
%   \includegraphics{scheme-one}\\
%   \caption{A scheme with no compound numbers.}
%   \label{scheme-one}
% \end{scheme}
% \end{verbatim}
% will lead to the appearance of a scheme as requested
% (Scheme~\ref{scheme-one}). By default, the positioning of |scheme|
% floats follows the standard LaTeX system (positioning at the top
% of a page is preferred). As shown in the example, the use of
% positional modifiers is allowed. The |float| package is loaded by
% |chemscheme|, allowing the use of the |[H]| positional directive,
% meaning \emph{really} here.\footnote{|memoir| users should note
% that |float| cannot be used with this document class.  The internal
% |memoir| system for float placement is thus in use in this case.}
% Labelling and referencing schemes follows the LaTeX conventions.
% So for example, to reference Scheme~\ref{scheme-one}, you type
% \begin{verbatim}
% Scheme~\ref{scheme-one}
% \end{verbatim}
%
% \DescribeMacro{\listofschemes}
% 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, taking a single optional argument \oarg{Title},
% which by default is ``List of Schemes.''  The output of the
% \cmd{\listofschemes} command is illustrated below.
% \listofschemes
%
% \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. Schemes may be numbered within chapters
% (Scheme~1.1, Scheme~1.2, \emph{etc.}~by loading the package with the
% [chapter] option.
%
% \DescribeMacro{\schemename}
% \DescribeMacro{\listschemes}
% Two macros are provided to allow the user to re-define the name of
% schemes and the title of the list of schemes in a consistent manner
% (independent of document class).  Thus \cmd{\schemename} contains
% the text used in scheme captions (by default \schemename), and
% \cmd{\listschemes} contains the title of the scheme list (by
% default \listschemes).  Both may be freely re-defined.
%
% \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, provided that \emph{compilation occurs in LaTeX (DVI) mode
% and not using pdfLaTeX}.\footnote{Of course, both may be using the
% pdfTeX engine; it is the output mode that is important.}
%
% \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 (\textsc{eps}) files
% The most popular chemistry drawing package, \textsc{ChemDraw},
% is able to do this from the \texttt{Save As \ldots} dialog.
% \DescribeMacro{\chemschemerefmarker}
% The positions where the auto-labels should be positioned have to be
% marked in the \textsc{eps} file.  The marker should consist of an
% ``indicator'' that the text is to be replaced, followed by a
% reference number or letter.  The ``indicator'' text should be the
% same in all graphics; it is stored in \cmd{\chemschemerefmarker},
% and has default value \textsf{\chemschemerefmarker}.  Thus the
% graphics should contain labels \textsf{\chemschemerefmarker1},
% \textsf{\chemschemerefmarker2}, \emph{etc.} A suitable unmodified
% graphic is shown in Scheme~\ref{scheme-two-uned}.
% \begin{scheme}[ht]
%   \centering
%   \includegraphics{scheme-two}\\
%   \caption{A scheme with temporary compound numbers.}
%   \label{scheme-two-uned}
% \end{scheme}
%
% The value of \cmd{\chemschemerefmarker} may be altered as normal
% using \cmd{\renewcommand}, so for example to use \textsf{XXX}
% as the indicator for replacement, you would execute
% |\renewcommand{\chemeschemerefmarker}{XXX}|.
%
% \DescribeMacro{\chemschemeref}
% In the second step, the command \cmd{\chemschemeref} is used to
% indicate the mapping of the temporary markers to the
% automatically-managed numbering. The syntax of the command
% is \cmd{\chemschemeref}\marg{temp-marker}\marg{label}, where
% \meta{temp-marker} is the unique marker used in the graphic,
% and \meta{label} is the name assigned to the compound by the user.
% Each replacement requires a separate \cmd{\chemschemeref}, all
% of which should appear before the relevant \cmd{\includegraphics}
% command.  Notice that \meta{temp-marker} only contains the
% unique part of the temporary marker. Thus using the default
% indicator \textsf{\chemschemerefmarker}, the \textsc{eps} file
% might contain \textsf{\chemschemerefmarker1} and \meta{temp-marker}
% would be \textsf{1}.
%
% 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
% Scheme~\ref{scheme-two-uned}, in the \textsc{eps} file these are
% labelled \textsf{TMP1} and \textsf{TMP2}, respectively. To relabel
% these as \CNlabel{IMesHCl} and \CNlabel{IMes}, the following is
% needed:
% \begin{scheme}[ht]
%   \centering
%   \chemschemeref{1}{IMesHCl}
%   \chemschemeref{2}{IMes}
%   \includegraphics{scheme-two}\\
%   \caption{A scheme with automated compound numbers.}
%   \label{scheme-two}
% \end{scheme}
% \begin{verbatim}
% \begin{scheme}[ht]
%   \centering
%   \chemschemeref{1}{IMesHCl}
%   \chemschemeref{2}{IMes}
%   \includegraphics{scheme-two}\\
%   \caption{A scheme with automated compound numbers.}
%   \label{scheme-two}
% \end{scheme}
% \end{verbatim}
% It is important to notice that the chemical labels must be defined
% \emph{before} the use of \cmd{\chemschemeref}, or odd things may
% happen (most likely your document will not compile with strange
% errors). Also 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{\chemschemerefsub}
% 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{\chemschemerefsub} 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{\chemschemerefformat}
% 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{\chemschemerefformat}. The additional
% formatting applied within schemes may be altered by redefining
% \cmd{\chemschemerefformat}.  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{verbatim}
% \usepackage[scaled=0.95]{helvet}
% \end{verbatim}
% The \textsc{ChemDraw} file used to generate the example schemes
% is included with the package, as |chemscheme.cdx|.
%
% \subsection{Managing chemical numbering\label{packages}}
%
% The |chemscheme| package can use one of two packages for management
% of chemical numbering.  Both |bpchem| and |chemcompounds| are
% supported: |bpchem| is the default, and |chemcompounds| is requested
% by loading |chemescheme| with the [chemcompounds] option.  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.  In either case, the user should define
% the chemical label \emph{before} it is referenced by
% \cmd{\chemschemeref}.  Errors are very likely to occur if this is
% not done.
%
% \section{Known issues}
%
% The number replacement code relies on the use of |psfrag|, which
% can only be applied to \textsc{eps} graphics.  Thus, users of
% pdfLaTeX will not benefit form the automated number replacement.
% For final compilation directly to \textsc{pdf}, it may be
% preferable to modify the graphics files and use |epstopdf| to
% include the files. The alternative is to use the more
% traditional route \textsc{dvi} $\to$ \textsc{ps} $\to$
% \textsc{pdf}.
%
% Currently, the names of schemes are only available in English. If
% the correct translations are provided, the package author will
% aim to incorporate the appropriate code.
