% CITES (style option to DARTICLE) is an extracted and changed
% part of the AIP style written by Charles Karney (Karney@PPC.MFEnet).
% CITES DOCUMENT SUBSTYLE -- released 15 March 1988
%
% To use this give CITES as an optional argument to \documentstyle.  The
% main style should be DARTICLE.  E.g.,
%     \documentstyle[12pt,german,cites]{darticle}
 
% This provides
% (1) Superscript reference numbers in citation and bibliography.
%     This is done by calling  \numcite  after \begin{document}.
%     You should put the references in the logically correct place, e.g.
%     "...  as is given by Landau \cite{landau}.  Next sentence ..."
%     \cite takes care of removing the preceding spaces and putting the
%     reference after the punctuation (e.g, "...  Landau.$~7$ ...").
 
% (2) Three or more consecutive reference numbers are represented as a
%     range.  Thus 1,3,4,5,6,8,9 is printed as 1,3--6,8,9.  No sorting is
%     performed; i.e., 1,3,2 is printed as such.
%     The cites style does this by default.
 
% (3) \citenum and \citea give you more control over the appearance of
%     the citations.  \citenum emits the plain citation number without
%     ornament as in "...  as shown in Ref.~\citenum{foo}.".  \citea puts
%     it's argument into the ornamentation for citations.
%     Thus \cite{foo} is equivalent to \citea{\citenum{foo}}.
 
% (4) \bibnum{p} prints entries of the thebibliography environment in the
%     form     #.
%     \bibnum{k} prints entries of the thebibliography environment in the
%     form    [#]
%     \bibnum{h} prints entries of the thebibliography environment in the
%     form    $^{#1}$
%     Default is \bibnum{k}.
%     If \numcite is used, \bibnum should appear after it.

%   CHANGES
%  06.04.89  G. Kruljac, kruljac@ds0mpi11
%            - inserted commands \refincount and \@refincount to
%              offer a possibility for citation numbering inside
%              chapters, sections,...
%              Initially it is empty. The user can define it by i.e.
%              \refincount{\thechapter.} or \refincount{\thesubsection.}
%
%            - corrections inside thebibliography for leftmargin
%              evaluations
