32 % This package reimplements the LaTeX \cite command to be used for various
33 % citation styles, both author-year and numerical. It accepts BibTeX
34 % output intended for many other packages, and therefore acts as a
35 % general, all-purpose citation-style interface.
36 %
37 % With standard numerical .bst files, only numerical citations are
38 % possible. With an author-year .bst file, both numerical and
39 % author-year citations are possible.
40 %
41 % If author-year citations are selected, \bibitem must have one of the
42 %   following forms:
43 %   \bibitem[Jones et al.(1990)]{key}...
44 %   \bibitem[Jones et al.(1990)Jones, Baker, and Williams]{key}...
45 %   \bibitem[Jones et al., 1990]{key}...
46 %   \bibitem[\protect\citeauthoryear{Jones, Baker, and Williams}{Jones
47 %       et al.}{1990}]{key}...
48 %   \bibitem[\protect\citeauthoryear{Jones et al.}{1990}]{key}...
49 %   \bibitem[\protect\astroncite{Jones et al.}{1990}]{key}...
50 %   \bibitem[\protect\citename{Jones et al., }1990]{key}...
51 %   \harvarditem[Jones et al.]{Jones, Baker, and Williams}{1990}{key}...
52 %
53 % This is either to be made up manually, or to be generated by an
54 % appropriate .bst file with BibTeX.
55 %                            Author-year mode     ||   Numerical mode
56 % Then, \citet{key}  ==>>  Jones et al. (1990)    ||   Jones et al. [21]
57 %       \citep{key}  ==>> (Jones et al., 1990)    ||   [21]
58 % Multiple citations as normal:
59 % \citep{key1,key2}  ==>> (Jones et al., 1990; Smith, 1989) || [21,24]
60 %                           or  (Jones et al., 1990, 1991)  || [21,24]
61 %                           or  (Jones et al., 1990a,b)     || [21,24]
62 % \cite{key} is the equivalent of \citet{key} in author-year mode
63 %                         and  of \citep{key} in numerical mode
64 % Full author lists may be forced with \citet* or \citep*, e.g.
65 %       \citep*{key}      ==>> (Jones, Baker, and Williams, 1990)
66 % Optional notes as:
67 %   \citep[chap. 2]{key}    ==>> (Jones et al., 1990, chap. 2)
68 %   \citep[e.g.,][]{key}    ==>> (e.g., Jones et al., 1990)
69 %   \citep[see][pg. 34]{key}==>> (see Jones et al., 1990, pg. 34)
70 %  (Note: in standard LaTeX, only one note is allowed, after the ref.
71 %   Here, one note is like the standard, two make pre- and post-notes.)
72 %   \citealt{key}          ==>> Jones et al. 1990
73 %   \citealt*{key}         ==>> Jones, Baker, and Williams 1990
74 %   \citealp{key}          ==>> Jones et al., 1990
75 %   \citealp*{key}         ==>> Jones, Baker, and Williams, 1990
76 % Additional citation possibilities (both author-year and numerical modes)
77 %   \citeauthor{key}       ==>> Jones et al.
78 %   \citeauthor*{key}      ==>> Jones, Baker, and Williams
79 %   \citeyear{key}         ==>> 1990
80 %   \citeyearpar{key}      ==>> (1990)
81 %   \citetext{priv. comm.} ==>> (priv. comm.)
82 %   \citenum{key}          ==>> 11 [non-superscripted]
83 % Note: full author lists depends on whether the bib style supports them;
84 %       if not, the abbreviated list is printed even when full requested.
85 %
86 % For names like della Robbia at the start of a sentence, use
87 %   \Citet{dRob98}         ==>> Della Robbia (1998)
88 %   \Citep{dRob98}         ==>> (Della Robbia, 1998)
89 %   \Citeauthor{dRob98}    ==>> Della Robbia
90 %
91 %
92 % Citation aliasing is achieved with
93 %   \defcitealias{key}{text}
94 %   \citetalias{key}  ==>> text
95 %   \citepalias{key}  ==>> (text)
96 %
97 % Defining the citation mode and punctual (citation style)
98 %   \setcitestyle{<comma-separated list of keywords, same
99 %     as the package options>}
100 % Example: \setcitestyle{square,semicolon}
101 % Alternatively:
102 % Use \bibpunct with 6 mandatory arguments:
103 %    1. opening bracket for citation
104 %    2. closing bracket
105 %    3. citation separator (for multiple citations in one \cite)
106 %    4. the letter n for numerical styles, s for superscripts
107 %        else anything for author-year
108 %    5. punctuation between authors and date
109 %    6. punctuation between years (or numbers) when common authors missing
110 % One optional argument is the character coming before post-notes. It
111 %   appears in square braces before all other arguments. May be left off.
112 % Example (and default) \bibpunct[, ]{(}{)}{;}{a}{,}{,}
113 %
114 % To make this automatic for a given bib style, named newbib, say, make
115 % a local configuration file, natbib.cfg, with the definition
116 %   \newcommand{\bibstyle@newbib}{\bibpunct...}
117 % Then the \bibliographystyle{newbib} will cause \bibstyle@newbib to
118 % be called on THE NEXT LATEX RUN (via the aux file).
119 %
120 % Such preprogrammed definitions may be invoked anywhere in the text
121 %  by calling \citestyle{newbib}. This is only useful if the style specified
122 %  differs from that in \bibliographystyle.
123 %
124 % With \citeindextrue and \citeindexfalse, one can control whether the
125 % \cite commands make an automatic entry of the citation in the .idx
126 % indexing file. For this, \makeindex must also be given in the preamble.
127 %
128 % Package Options: (for selecting punctuation)
129 %   round  -  round parentheses are used (default)
130 %   square -  square brackets are used   [option]
131 %   curly  -  curly braces are used      {option}
132 %   angle  -  angle brackets are used    <option>
133 %   semicolon  -  multiple citations separated by semi-colon (default)
134 %   colon  - same as semicolon, an earlier confusion
135 %   comma  -  separated by comma
136 %   authoryear - selects author-year citations (default)
137 %   numbers-  selects numerical citations
138 %   super  -  numerical citations as superscripts
139 %   sort   -  sorts multiple citations according to order in ref. list
140 %   sort&compress   -  like sort, but also compresses numerical citations
141 %   compress - compresses without sorting
142 %   longnamesfirst  -  makes first citation full author list
143 %   sectionbib - puts bibliography in a \section* instead of \chapter*
144 %   merge - allows the citation key to have a * prefix,
145 %           signifying to merge its reference with that of the previous citation.
146 %   elide - if references are merged, repeated portions of later ones may be removed.
147 %   mcite - recognizes and ignores the * prefix for merging.
148 % Punctuation so selected dominates over any predefined ones.
149 % Package options are called as, e.g.
150 %        \usepackage[square,comma]{natbib}
151 % LaTeX the source file natbib.dtx to obtain more details
152 % or the file natnotes.tex for a brief reference sheet.
