% \section{Introduction and motivation}
% While \LaTeX{} is a powerful tool for mathematical or physical issues the typesetting of chemistry derived problems is still a little bit annoying. When I wrote my thesis in organic chemistry I missed a package which produces chemical schemes as easy as you include a graphic into your document. I simply wanted to draw my structures in \textsc{ChemDraw}, inlcude them into my document and label them.
%
% The packages \textsf{chemscheme} and \textsf{chemnum} offer a possibility to rerender image files for this purpose. Nevertheless, they only modify a scheme that already exists. This means, that arrows, margins, alignments and other parameters cannot be defined or changed globally in your document.
%
% By using the \TikZ{} and the \FL{} package (which has actually been written as slave of this package) the \CSX{} package meets all these requirements (see example \ref{fig.intro.1}).
%
%
%
% \section{Usage}
% \noindent\DescribeMacro{\usepackage}
% |\usepackage[<options>]{chemschemex}|\vspace{0.5em}
%
% \noindent The command above will load the \CSX{} package. It requires the packages \textsf{xkeyval}, \textsf{etextools}, \textsf{xargs}, \textsf{ifthen}, \textsf{suffix}, \TikZ{}, \textsf{graphicx}, and \FL{}. I strongly recommend to read the documentation of the \FL{} package because all referencing functions are provided by this package. It contains a lot of useful options that are not described in this documentation.

% \section{User commands}
%
% \subsection{Basic commands}
% \noindent\DescribeMacro{\customstruct}
% |\customstruct[<TikZ-capt>][<TikZ-obj>]{<capt>}{<obj>}|\vspace{0.5em}
%
% \noindent The |\customstruct| command typesets the object \textcolor{red}{|<obj>|} in the first row of a \TikZ{} matrix and the caption \textcolor{blue}{|<capt>|} in the second row. The caption is supposed to be given as comma-separated list of label(s) and text. The two optional arguments |<TikZ-capt>| and |<TikZ-obj>| can be used to pass options to \TikZ{} elements (for further information see section \ref{custom}). All the following structure commands are based on |\customstruct|.
%
% \begin{minipage}{0.27\linewidth}
% \begin{Chemscheme}
% \customstruct[nodes={draw=blue}]
% [draw=red]
% {{{label1:},{text}},{{ll2:},{a longer text}}}
% {object e.g. image}
% \end{Chemscheme}
% \end{minipage}
% \begin{minipage}{0.6\linewidth}
% \begin{verbatim}
% \customstruct[nodes={draw=blue}][draw=red]
% {{{label1:},{text}},
% {{ll2:},{a longer text}}}
% {object e.g. image}
% \end{verbatim}
% \end{minipage}
%
%
% \vspace{3ex}\noindent\DescribeMacro{\CSXimage}
% |\CSXimage[<img-opt>]{<img>}|\vspace{0.5em}
%
% \noindent The |\CSXimage| command includes the image |<img>| using the global options |<global-img-opt>| defined by the |image| option (see section \ref{image}) and the options given by |<img-opt>|. This command is used in all the following structure commands and expands to |\includegraphics[<global-img-opt>,<img-opt>]{<img>}|.
%
%
%
% \subsection{Structure commands}
% \vspace{3ex}\noindent\DescribeMacro{\struct}
% |\struct[<capt>][<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<img>}|\vspace{0.5em}
%
% \noindent The |\struct| command inlcudes the image |<img>|, sets a fancylabel (therefore it uses |<img>| as marker and |<fam>| as family, default: |<fam>|=|CSX|; the use of families is described in the \FL{} package) and prints it. If a |<caption>| is given, it will also print the caption behind the label. The macro |\CSXlabelsep| can be changed with the |labelseparator| option.
%
% \begin{minipage}{0.2\linewidth}
% \struct[text]{maleimid}
% \end{minipage}
% \begin{minipage}{0.79\linewidth}
% \begin{verbatim}
% \struct[text]{maleimid}
% expands to:
% \customstruct{{{\fancylabel[CSX]{maleimid}\CSXlabelsep},{}}}
% {\CSXimage{maleimid}}
% \end{verbatim}
% \end{minipage}
%
%
% \newpage
% \vspace{3ex}\noindent\DescribeMacro{\structalt}
% |\structalt[<capt>][<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<img>}{<alt-img>}|\vspace{0.5em}
%
% \noindent The |\structalt| command includes an image |<alt-img>| but the labeling corresponds to |<img>|.
%
% \begin{minipage}{0.2\linewidth}
% \structalt{product}{product_num}
% \end{minipage}
% \begin{minipage}{0.7\linewidth}
% \begin{verbatim}
% \structalt{product}{product_num}
% expands to:
% \customstruct{{{\fancylabel[CSX]{product}},{}}}
% {\CSXimage{product_num}}
% \end{verbatim}
% \end{minipage}
%
%
% \vspace{3ex}\noindent\DescribeMacro{\struct*}
% \noindent\DescribeMacro{\structalt*}
% |\struct*[<capt>][<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<img>}|\\
% |\structalt*[<capt>][<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<img>}{<alt-img>}|\vspace{0.5em}
%
% \noindent The |\struct*| and |\structalt*| commands do the same as the corresponding nonstarred versions but use |\fancylabel*| instead of |\fancylabel|. This means, that a label for this structure will be defined but not printed.
%
% \begin{minipage}{0.2\linewidth}
% \struct*{maleimid}
% \end{minipage}
% \begin{minipage}{0.7\linewidth}
% \begin{verbatim}
% \struct*{maleimid}
% expands to:
% \customstruct{{{\fancylabel*[CSX]{maleimid}},{}}}
% {\CSXimage{maleimid}}
% \end{verbatim}
% \end{minipage}
%
%
% \vspace{3ex}\noindent\DescribeMacro{\struct-}
% |\struct-[<capt>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<img>}|\vspace{0.5em}
%
% \noindent The |\struct-| command includes an image |<img>| without any labeling.
%
% \begin{minipage}{0.2\linewidth}
% \struct-[text]{maleimid}
% \end{minipage}
% \begin{minipage}{0.7\linewidth}
% \begin{verbatim}
% \struct-[text]{maleimid}
% expands to:
% \customstruct{{{},{text}}}
% {\CSXimage{maleimid}}
% \end{verbatim}
% \end{minipage}
%
%
%
%
% \vspace{3ex}\noindent\DescribeMacro{\newstruct}
% |\newstruct[<sublabels>]{<img>}{<structname>}{<Structname>}{<abbr>}|\vspace{0.5em}
%
% \noindent If you want to use substructures you have to define them in the preamble. The optional argument |<sublabels>| is a comma-separated list of subcaptions. Whenever you want to refer to them you just have to use their numbers. In this example the first entry (|R=H|) gets the number 1, the second entry (|R=Me|) gets the number 2 and so on. If you use a structure without substructures it is not necessary to use |\newstruct|. However, the |\newstruct| command defines the name (and Name) und abbreviation of the structure what allows you to use the commands |\structname|, |\Structname| and |\structabbr| for this structure.\vspace{2ex}
%
% \begin{minipage}{0.9\linewidth}
% \begin{verbatim}
%\newstruct[{R=H},{R=Me},{R=Ph}]{product}{}{}{}
% \end{verbatim}
% \end{minipage}
%
% \vspace{3ex}\noindent\textbf{Note:} All of the following structure commands assume that |\newstruct| has been used for the filename |<img>| before.
%
% \vspace{3ex}\noindent\DescribeMacro{\Struct}
% |\Struct[<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<sublabels>}{<img>}|\vspace{0.5em}
%
% \noindent To use the |\Struct| command, the structure and its substructure have to be defined by the |\newstruct| command. It inlcudes the image |<img>|, sets the sublabels given in the comma-separated list of |<sublabels>| and prints each sublabel with the subcaption previously given to the |\newstruct| command (one line per sublabel).
%
% \begin{minipage}{0.2\linewidth}
% \Struct{1,2,3}{product}
% \end{minipage}
% \begin{minipage}{0.7\linewidth}
% \begin{verbatim}
% \Struct{1,2,3}{product}
% expands to:
% \customstruct{{{\fancysublabel[CSX]{product}{1}\CSXlabelsep},{R=H}},
% {{\fancysublabel[CSX]{product}{2}\CSXlabelsep},{R=Me}},
% {{\fancysublabel[CSX]{product}{3}\CSXlabelsep},{R=Ph}}}
% {\CSXimage{product}}
% \end{verbatim}
% \end{minipage}
%
% \vspace{3ex}\noindent\DescribeMacro{\Struct*}
% |\Struct*[<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<sublabels>}{<img>}|\vspace{0.5em}
%
% \noindent To use the |\Struct*| command, the structure and its substructure have to be defined by the |\newstruct| command. It inlcudes the image |<filename>|, sets the sublabels given in the comma-separated list of |<sublabels>| and prints each sublabel without its subcaption previously given to the |\newstruct| command.
%
% \begin{minipage}{0.2\linewidth}
% \Struct*{1,3}{product}
% \end{minipage}
% \begin{minipage}{0.7\linewidth}
% \begin{verbatim}
% \Struct*{1,3}{product}
% expands to:
% \customstruct{{{\fancysublabel[CSX]{product}{1,3}},{}}}
% {\CSXimage{product}}
% \end{verbatim}
% \end{minipage}
%
%
% \vspace{3ex}\noindent\DescribeMacro{\Structalt}
% |\Structalt[<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<sublabels>}{<img>}{<alt-img>}|\vspace{0.5em}
%
% \noindent Works like the |\Struct| command but includes the image |<alt-img>|. Labeling corresponds to |<img>|.
%
%
% \vspace{3ex}\noindent\DescribeMacro{\Structalt*}
% |\Structalt*[<fam>][<img-opt>][<TikZ-capt>][<TikZ-obj>]{<sublabels>}{<img>}{<alt-img>}|\vspace{0.5em}
%
% \noindent Works like the |\Struct*| command but includes the image |<alt-img>|. Labeling corresponds to |<img>|.
%
%
% \vspace{3ex}\noindent\DescribeMacro{\structname}
% |\structname{<img>}|\vspace{0.5em}
%
% \noindent Prints the name of the structure |<img>| that has been previously defined by the |\newstruct| command. This command is recommended for the chemical name without a leading capital letter (inside a sentence).
%
%
% \vspace{3ex}\noindent\DescribeMacro{\Structname}
% |\Structname{<img>}|\vspace{0.5em}
%
% \noindent Prints the name of the structure |<img>| that has been previously defined by the |\newstruct| command. This command is recommended for the chemical name with a leading capital letter (at the beginning of a sentence).
%
%
% \vspace{3ex}\noindent\DescribeMacro{\structabbr}
% |\structabbr{<img>}|\vspace{0.5em}
%
% \noindent Prints the abbreviation of the structure |<img>| that has been previously defined by the |\newstruct| command.
%
%
%
%
% \subsection{The Chemscheme environment}
%
% \noindent\DescribeEnv{Chemscheme}
% |\begin{Chemscheme}...structure code...\end{Chemscheme}|\vspace{0.5em}
%
% \noindent If a structure command appears outside a |Chemscheme| environment each command will typeset the image and caption in its own matrix. This causes no kind of adjustment.
%
% \begin{minipage}{0.3\linewidth}
% \struct{cp}
% \struct[long caption]{maleimid}
% \end{minipage}
% \begin{minipage}{0.59\linewidth}
% \begin{verbatim}
% \struct{cp}
% \struct[long caption]{maleimid}
% \end{verbatim}
% \end{minipage}
%
% \noindent But if structure commands appear inside a |Chemscheme| environment all images and captions are printed in one matrix. This causes adjustment of the image (by default center) and the caption row (by default top) according to the \TikZ{} style |CSXmatrix|.
%
%
% \begin{minipage}{0.3\linewidth}
% \begin{Chemscheme}
% \struct{cp}
% \struct[long caption]{maleimid}
% \end{Chemscheme}
% \end{minipage}
% \begin{minipage}{0.59\linewidth}
% \begin{verbatim}
% \begin{Chemscheme}
% \struct{cp}
% \struct[long caption]{maleimid}
% \end{Chemscheme}
% \end{verbatim}
% \end{minipage}
%
%
% \vspace{3ex}\noindent\DescribeMacro{\ChemschemeNextRow}
% |\ChemschemeNextRow[<row-sep>]|\vspace{0.5em}
%
% \noindent If you want to use the matrix adjustment over multiple lines you can produce a 'linebreak' using the |\ChemschemeNextRow| command. The optional argument |<row-sep>| allows you to define the space between the rows.

% \section{Options}
% \subsection{The image option}\label{image}
% \noindent\DescribeMacro{image=}
% |\usepackage[image={<global-img-opt>}]{chemschemex}|\vspace{0.5em}
%
% \noindent All structure commands except |\customstruct| internally use the |\CSXimage| command to include pictures with |\includegraphics|. The |image| option allows you to define options that will be passed to any image that is inserted via |\CSXimage|. The default value is |image={scale=0.7}|.
%
%
% \subsection{The labelseparator option}
% \noindent\DescribeMacro{labelseparator=}
% |\usepackage[labelseparator=<value>]{chemschemex}|\vspace{0.5em}
%
% \noindent The |<value>| given by the |labelseparator| option is set behind every |\fancylabel| inside a structure command if some text follows. The value is saved in |\CSXlabelsep|. The default value is |labelseparator={:\,}|.
%
%\begin{Chemscheme}

% }
%\end{Chemscheme}
%
%
%
%
% \subsection{The arrowadvance option}
% \noindent\DescribeMacro{arrowadvance=}
% |\usepackage[arrowadvance=<length>]{chemschemex}|\vspace{0.5em}
%
% \noindent Every arrow with undefined length argument will be as long as its widest caption plus the length given by the |arrowadvance| option. This is also the minimal length of an arrow (when no captions are given). The default value is |arrowadvance=10pt|.
%
%
%
%
% \section{Customization and advanced examples}
% \subsection{Predefined \TikZ{} styles}\label{custom}
%
% \noindent There are a lot of \TikZ{} styles that are already defined by the \CSX{} package. The following two examples show the code that is generated by \CSX{} and hopefully help you to understand the function of each style. Some of them can be changed (\textcolor{green!75!black}{green}), some of them must not be changed (\textcolor{red}{red}) to prevent strange results or even errors. If you want to change fonts please use the \textcolor{blue}{blue} coloured styles instead of appending |font=| to any style since this will cause wrong calculations. The \textcolor{orange}{orange} entries are styles that are optional arguments of |\customstruct|.

% \subsection{Style adjustment -- some examples}
%
% \noindent As already mentioned above, please use the styles \textblue{|CSXlabelfont|} and \textblue{|CSXtextfont|} for any changes of the node font. This is necessary to ensure correct measurements. For local font adjustment of captions in structure commands use the optional argument \textorange{|<TikZ-capt>|}.
