% \begin{abstract}
% The |achemso| package provides a BibTeX style in accordance with
% the requirements of the journals of the American Chemical Society,
% along with a supporting LaTeX package file. Also provided is a
% BibTeX style file to be used for bibliography database listings.
% \end{abstract}
%
% \section{Introduction}
%
% Although synthetic chemists do not, in the main, use LaTeX for the
% preparation of journal articles, it would be nice to be able to use
% it for reports.  Some (mainly) physical chemistry journals do
% also accept LaTeX submissions, and so the need for BibTeX styles
% for chemistry is real. The package |achemso| provides for a BibTeX
% style and other support for articles and reports in the style of
% the American Chemical Society (A.C.S.).  Journals which use the
% standard A.C.S. citation style are summarised in
% \ref{tbl:journals}.
% \begin{table}
%   \begin{tabular}{>{\itshape}l>{\itshape}l}
%     \toprule
%     \upshape{Journal Title} & \upshape{Abbreviation} \\

% \end{table}
%
% This package consists of two BibTeX files (|achemso.bst|
% and |achemsol.bst|) along with a small LaTeX file |achemso.sty|.
% The naming of the package is slightly unusual, but follows from
% the need to pick a unique name.  To quote the documentation to the
% first version:
% \begin{quote}
%   [\dots] there is already a LaTeX 2.09 and
%   BibTeX style package called |acsarticle| and
%   |acs.bst|, which are not ``ACS'' as in `American Chemical
%   Society' (rather, this package is
%   formatting the output according to the instructions of
%   \emph{Advances in Control Systems}).  Hence, \emph{this}
%   new package had to be given another name.  The name of choice
%   was then |achemso|, which is made from the words
%   ``\emph{A}merican \emph{Chem}ical \emph{So}ciety''.
% \end{quote}
%
% \subsection{Change of maintainer}
%
% This package was initially released by Mats Dahlgren.  He no
% longer has time to devote to LaTeX development.  With his permission,
% the package has therefore been taken over by Joseph
% Wright, the maintainer of the the |rsc| package.  The majority of
% the package has been rebuilt and the BibTeX style file has been
% totally overhauled.  Any mistakes are entirely the fault of the
% new maintainer!
%
% \section{The BibTeX style files}
%
% The BibTeX style files implement the bibliographic style specified
% by the A.C.S.\ in \emph{The ACS Style Guide: A Manual for Authors
% and Editors}, on the A.C.S.\ website
% (\url{http://pubs.acs.org/books/references.shtml}) and in current
% A.C.S.~publications.  Some of this information can be
% contradictory; the consensus of current practice in the printed
% journals has been taken as the correct approach.
%
% \subsection{Additional record types}
%
% In general, the database record types supported here follow those
% in the standard BibTeX style files.  Four additional record types
% are provided:
% \begin{description}
%   \item[|patent|] A patent: formatting is similar to other record
%       types.  The data entry for this record type follows the
%       pattern used in |rsc.bst|: |journal| is used to hold
%       the patent type (\emph{e.g.} ``U.S. Pat.''), with the
%       patent number given in |pages|. Whilst this format is
%       non-standard, it is relatively easy to use and implement!
%   \item[|submitted|] Articles submitted to journals but not
%       yet accepted: appends ``submitted'' in a suitable fashion
%       to the entry.
%   \item[|inpress|] Articles in press: appends ``in press'' or,
%       if available, the DOI number assigned to the article.
%   \item[|remark|] A note with no other information to be
%       included.  Output consists purely of the |note| field.
% \end{description}
%
% \subsection{BibTeX database entry requirements}
%
% The requirements for entries in the BibTeX database are slightly
% different using |achemso.bst| to the standard style files. This
% is mainly because some fields are not cited in
% A.C.S.\ bibliographies.   In particular, journal articles do not
% require a title (as the |title| field is ignored).  Articles
% in books only need the title of the book; the title of the
% subunit (given in |title|) is again ignored.
%
% \subsection{The \textsf{annotate} field}
%
% The standard BibTeX styles use the |note| field for notes to be
% added to the citation.  However, it is common to want personal
% notes about references.  This is catered for using the |annotate|
% field.  The style |achemso| ignores the |annotate| field, whilst
% the |achemsol| style appends the |annotate| information to the
% bibliographic output.  Thus |achemsol| is intended for use in
% database maintenance, whilst |achemso| is for production
% bibliographies.
%
% \DescribeMacro{\refin}
% For use in the |annotate| field the macro \cmd{\refin}
% is defined in |achemso.bst| and |achemsol.bst|.
% The command takes a single argument \marg{text}, and
% gives the output \textbf{Referenced in: text}.
% This command takes one argument (normally text) which is
% preceded by the text ``\textbf{Referenced in:} \meta{text}''.
% The |\refin| command is intended for tracking citations
% ``backward'' through the database.  For example, this could be
% used to link citations in a database to the writers own papers.
%
% \subsection{Predefined journal abbreviations}
%
% A number of journal abbreviations are defined in the |.bst| files.
% The abbreviations cover a number A.C.S.\ journals, several other
% physical chemistry publications and other journals listed as
% highly cited by \emph{Chem.\ Abs.}  The interested user should
% consult the |.bst| files for full details.
%
% \section{The LaTeX Package}
%
% The current version of |achemso.sty| is a
% complete re-implementation of the functionality of the original
% file, designed to ensure greater compatibility with other packages.
% The only change for the user is that the bibliography section does
% \emph{not} start a new page when using the |article| document
% class. However, the package now supports all of the standard
% classes, and so the |report| class may be used to ensure a new
% page is started.
%
% \DescribeMacro{\bibliographystyle}
% Loading the |achemso| package adds the appropriate
% \cmd{\bibliographystyle} command to the LaTeX source.  As a result,
% subsequent \cmd{\bibliographystyle} statements will be ignored:
% a suitable warning is given.  The format of citations is altered
% (using the |cite| package), and the package ensures that the
% bibliography will be named ``References'' in all standard document
% types.\footnote{This only works if the |babel| package is
% \emph{not} loaded.}
%
%  The |achemso| package has three options: |note|,
%  |list|, and |number|:
% \begin{description}
%   \item[|note|] If the bibliography contains notes as well
%       as citations, then the section heading should be
%       ``References and Notes''.  This is altered by the
%       |note| package option.
%   \item[|number|] This option numbers the bibliography
%       section (using the |tocbibind| package), and causes it to
%       be entered in the Table of Contents.
%   \item[|list|] This option is intended for creating a listing
%       of the entire BibTeX database.  The BibTeX style is
%       changed to |achemsol|, which will output the additional
%       database field |annotate|, intended for personal notes
%       about a particular database entry.  It also adds the
%       BibTeX key for each citation as a marginal note to the
%       output, using the |showkeys| package.
% \end{description}

% \section{The Package Code}
%
%  The package code is not very complicated.  For the
%  interested reader(s), it is presented here.
%
% \begin{macro}{\ACSver}
% An identifying macro is provided, so that other packages
% can detect the version of achemso in use.
%    \begin{macrocode}
%<*package>
\def\ACSver{\texttt{achemso} v2.0 (2007/01/17)}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\ACS@sctnnmbr}
% \begin{macro}{\ACS@lst}
% \begin{macro}{\ACS@note}
% \changes{v2.0}{2007/01/17}{Boolean values made internal to package}
% Three Boolean values are used to handle the options.
%    \begin{macrocode}
\newif \ifACS@sctnnmbr \ACS@sctnnmbrfalse
\newif \ifACS@lst      \ACS@lstfalse
\newif \ifACS@note     \ACS@notefalse
%    \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
% The options are processed, and the |cite| package is loaded to
% sort and compress references correctly.  The ACS also have
% no gaps in between reference numbers, so the |nospace| option
% is used.
%    \begin{macrocode}
\DeclareOption{note}{\global\ACS@notetrue}
\DeclareOption{number}{\global\ACS@sctnnmbrtrue}
\DeclareOption{list}{\global\ACS@lsttrue}
\DeclareOption*{\OptionNotUsed}
\ProcessOptions
\RequirePackage[super,nospace]{cite}
%    \end{macrocode}
% If the |babel| package is loaded, the |note| option does not
% work.  So it is disabled here with a suitable warning.
%    \begin{macrocode}
 \@ifpackageloaded{babel}
  {\ACS@notefalse\PackageWarning{achemso}%
    {babel package loaded - note option disabled}}
  {\relax}
%    \end{macrocode}
% \begin{macro}{\ACS@biberror}
% The function \cmd{\ACS@biberror} is defined here to provide an
% easy way of generating a warning if there is no name for a
% bibliography section.  This will only happen with non-standard
% class files.
%     \begin{macrocode}
\def\ACS@biberror{\PackageError{achemso}%
  {No bibliography name command defined}\@eha}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\refname}
% \begin{macro}{\bibname}
% The |note| option renames the references section to
% ``References and Notes''.  This applies for all standard
% document classes.
% The term ``Bibliography'' is not used in chemistry, the value of
% \cmd{\bibname} is redefined here in all cases where it exists.
%     \begin{macrocode}
\ifx\refname\undefined
   \ifx\bibname\undefined
      \ACS@biberror
    \else
      \ifACS@note
        \renewcommand*{\bibname}{References and Notes}

        \renewcommand*{\bibname}{References}
      \fi
    \fi
 \else
   \ifACS@note
     \renewcommand*{\refname}{References and Notes}
   \fi
\fi
%    \end{macrocode}
% \end{macro}
% \end{macro}
% If the |number| option is set, the |tocbibind| package is
% used to number the bibliography.
% \changes{v2.0}{2007/01/17}{Switched to using \textsf{tocbibind}
% to produce number bibliography}
%    \begin{macrocode}
\ifACS@sctnnmbr
  \RequirePackage[numbib]{tocbibind}
\fi
%    \end{macrocode}
% \begin{macro}{\bibliographystyle}
% Depending on the package option, the bibliography style
% will either be |achemso| or |achemsol|.  The later is intended
% for listing the entire database.  The |list| option of the
% package selects this, and for listing also generates boxed
% labels for each reference.  The |showkeys| package provides
% this functionality.
% \changes{v2.0}{2007/01/17}{Replaced custom code with
% \textsf{showkeys} package}
%    \begin{macrocode}
\ifACS@lst
  \bibliographystyle{achemsol}
  \RequirePackage[notcite]{showkeys}
\else
  \bibliographystyle{achemso}
\fi
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\@biblabel}
% In order to re-format the bibliography labels, the easiest
% method is to redefine the \cmd{\@biblabel} macro from the LaTeX
% kernel.
%    \begin{macrocode}
\def\@biblabel#1{#1.}
%    \end{macrocode}
% \end{macro}
% \begin{macro}{\ACS@bibwarning}
% \begin{macro}{\bibliographystyle}
% To ensure that additional \cmd{\bibliographystyle} commands in the
% source are killed off.  The \cmd{\ACS@bibwarning} provides a clean
% method of generating the warning message.
% \changes{v2.0}{2007-01-17}{Command ignored in document body}
