+ % This package reimplements the LaTeX \cite command to be used for various
+ % citation styles, both author-year and numerical. It accepts BibTeX
+ % output intended for many other packages, and therefore acts as a
+ % general, all-purpose citation-style interface.
+ %
+ % With standard numerical .bst files, only numerical citations are
+ % possible. With an author-year .bst file, both numerical and
+ % author-year citations are possible.
+ %
+ % If author-year citations are selected, \bibitem must have one of the
+ %   following forms:
+ %   \bibitem[Jones et al.(1990)]{key}...
+ %   \bibitem[Jones et al.(1990)Jones, Baker, and Williams]{key}...
+ %   \bibitem[Jones et al., 1990]{key}...
+ %   \bibitem[\protect\citeauthoryear{Jones, Baker, and Williams}{Jones
+ %       et al.}{1990}]{key}...
+ %   \bibitem[\protect\citeauthoryear{Jones et al.}{1990}]{key}...
+ %   \bibitem[\protect\astroncite{Jones et al.}{1990}]{key}...
+ %   \bibitem[\protect\citename{Jones et al., }1990]{key}...
+ %   \harvarditem[Jones et al.]{Jones, Baker, and Williams}{1990}{key}...
+ %
+ % This is either to be made up manually, or to be generated by an
+ % appropriate .bst file with BibTeX.
+ %                            Author-year mode     ||   Numerical mode
+ % Then, \citet{key}  ==>>  Jones et al. (1990)    ||   Jones et al. [21]
+ %       \citep{key}  ==>> (Jones et al., 1990)    ||   [21]
+ % Multiple citations as normal:
+ % \citep{key1,key2}  ==>> (Jones et al., 1990; Smith, 1989) || [21,24]
+ %                           or  (Jones et al., 1990, 1991)  || [21,24]
+ %                           or  (Jones et al., 1990a,b)     || [21,24]
+ % \cite{key} is the equivalent of \citet{key} in author-year mode
+ %                         and  of \citep{key} in numerical mode
+ % Full author lists may be forced with \citet* or \citep*, e.g.
+ %       \citep*{key}      ==>> (Jones, Baker, and Williams, 1990)
+ % Optional notes as:
+ %   \citep[chap. 2]{key}    ==>> (Jones et al., 1990, chap. 2)
+ %   \citep[e.g.,][]{key}    ==>> (e.g., Jones et al., 1990)
+ %   \citep[see][pg. 34]{key}==>> (see Jones et al., 1990, pg. 34)
+ %  (Note: in standard LaTeX, only one note is allowed, after the ref.
+ %   Here, one note is like the standard, two make pre- and post-notes.)
+ %   \citealt{key}          ==>> Jones et al. 1990
+ %   \citealt*{key}         ==>> Jones, Baker, and Williams 1990
+ %   \citealp{key}          ==>> Jones et al., 1990
+ %   \citealp*{key}         ==>> Jones, Baker, and Williams, 1990
+ % Additional citation possibilities (both author-year and numerical modes)
+ %   \citeauthor{key}       ==>> Jones et al.
+ %   \citeauthor*{key}      ==>> Jones, Baker, and Williams
+ %   \citeyear{key}         ==>> 1990
+ %   \citeyearpar{key}      ==>> (1990)
+ %   \citetext{priv. comm.} ==>> (priv. comm.)
+ % Note: full author lists depends on whether the bib style supports them;
+ %       if not, the abbreviated list is printed even when full requested.
+ %
+ % For names like della Robbia at the start of a sentence, use
+ %   \Citet{dRob98}         ==>> Della Robbia (1998)
+ %   \Citep{dRob98}         ==>> (Della Robbia, 1998)
+ %   \Citeauthor{dRob98}    ==>> Della Robbia
+ %
+ %
+ % Citation aliasing is achieved with
+ %   \defcitealias{key}{text}
+ %   \citetalias{key}  ==>> text
+ %   \citepalias{key}  ==>> (text)
+ %
+ % Defining the citation style of a given bib style:
+ % Use \bibpunct (in the preamble only) with 6 mandatory arguments:
+ %    1. opening bracket for citation
+ %    2. closing bracket
+ %    3. citation separator (for multiple citations in one \cite)
+ %    4. the letter n for numerical styles, s for superscripts
+ %        else anything for author-year
+ %    5. punctuation between authors and date
+ %    6. punctuation between years (or numbers) when common authors missing
+ % One optional argument is the character coming before post-notes. It
+ %   appears in square braces before all other arguments. May be left off.
+ % Example (and default) \bibpunct[, ]{(}{)}{;}{a}{,}{,}
+ %
+ % To make this automatic for a given bib style, named newbib, say, make
+ % a local configuration file, natbib.cfg, with the definition
+ %   \newcommand{\bibstyle@newbib}{\bibpunct...}
+ % Then the \bibliographystyle{newbib} will cause \bibstyle@newbib to
+ % be called on THE NEXT LATEX RUN (via the aux file).
+ %
+ % Such preprogrammed definitions may be invoked in the text (preamble only)
+ %  by calling \citestyle{newbib}. This is only useful if the style specified
+ %  differs from that in \bibliographystyle.
+ %
+ % With \citeindextrue and \citeindexfalse, one can control whether the
+ % \cite commands make an automatic entry of the citation in the .idx
+ % indexing file. For this, \makeindex must also be given in the preamble.
+ %
+ % LaTeX2e Options: (for selecting punctuation)
+ %   round  -  round parentheses are used (default)
+ %   square -  square brackets are used   [option]
+ %   curly  -  curly braces are used      {option}
+ %   angle  -  angle brackets are used    <option>
+ %   colon  -  multiple citations separated by colon (default)
+ %   comma  -  separated by comma
+ %   authoryear - selects author-year citations (default)
+ %   numbers-  selects numerical citations
+ %   super  -  numerical citations as superscripts
+ %   sort   -  sorts multiple citations according to order in ref. list
+ %   sort&compress   -  like sort, but also compresses numerical citations
+ %   longnamesfirst  -  makes first citation full author list
+ %   sectionbib - puts bibliography in a \section* instead of \chapter*
+ % Punctuation so selected dominates over any predefined ones.
+ % LaTeX2e options are called as, e.g.
+ %        \usepackage[square,comma]{natbib}
+ % LaTeX the source file natbib.dtx to obtain more details
+ % or the file natnotes.tex for a brief reference sheet.
