-\ProvidesPackage{natbib}
-        [2009/07/16 8.31 (PWD, AO)]
-
- % 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.)
- %   \citenum{key}          ==>> 11 [non-superscripted]
- % 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 mode and punctual (citation style)
- %   \setcitestyle{<comma-separated list of keywords, same
- %     as the package options>}
- % Example: \setcitestyle{square,semicolon}
- % Alternatively:
- % Use \bibpunct 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 anywhere in the text
- %  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.
- %
- % Package 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>
- %   semicolon  -  multiple citations separated by semi-colon (default)
- %   colon  - same as semicolon, an earlier confusion
- %   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
- %   compress - compresses without sorting
- %   longnamesfirst  -  makes first citation full author list
- %   sectionbib - puts bibliography in a \section* instead of \chapter*
- %   merge - allows the citation key to have a * prefix,
- %           signifying to merge its reference with that of the previous citation.
- %   elide - if references are merged, repeated portions of later ones may be removed.
- %   mcite - recognizes and ignores the * prefix for merging.
- % Punctuation so selected dominates over any predefined ones.
- % Package 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.
