% How this package is organized:
% ------------------------------
% - Implementing `search for substring'
% - \AfterTheBibliography{} hook
% - Options declaration (search for substring needed here)
%     alf, num (default)
%     alfantigo, experimental (default)
%     biblabel-on-margin
%     sem-bibtex (apply settings without count with code in .bbl)
%     no-abnt-option-file (in case one defines its own options file)
%     recuo (then makes bibitem indent 1.8em) (default: NO indentation)
%     recuo=<length> (sets custom indentation)
%     indent   is an alias for recuo (indent or indent=<length>)
%     versalete  author in alf mode as with smallcaps
%     other options are considered "\citeoption's" (mechanism includes a
%       list that stores non defined options, and in \AtBeginDocument,
%       \citeoption acts over this list)
% - allocing auxiliar variables
% - \citeoption
%     Similar to \nocite, but does not complain about obviously not defined
%     citations. Intented to access options of abnTeX's bibtex styles.
% - \bibliography
%     extra care to auto include abnt-options as bibliography database (if
%     needed)
% - \bibliographystyle
%     if none is given, the style correspondent to the package style in
%     use (alf or num) is given.
% - Style customization
%     \authorcapstyle, \authorstyle, \yearstyle, \optionaltextstyle
%     (detail: \authorcapstyle's default setting uses \smaller from relsize
%     package, but only if package is present.)
% - \bibitem
%     defines action of \bibitem by its subcommands. Comatibility with old
%     abnt-alf is present.
% - \hiddenbibitem
%     creates an empty bibliography entry buts creates all labels.
% - \abntrefinfo
%     From the creation of abntcite, options are present as a separated
%     command. This enables compatibility with any bibtex style.
%
% - \cite
%     This command depends on if the style is alf or num
%     If alf, then \cite produces (<explicit (capital)>, <year>)
%     If num, then \cite produces a superscript with [<implicit (lowercase)>]
% - \citeonline
%     This command depends on if the style is alf or num
%     If alf, \citeonline produces <implicit (lowercase)>, (<year>)
%     If num, \citeonline then produces <implicit (lowercase)>
% - \citeyear
%     Produces <year>
% - \citeauthor
%     Produces <explicit (capital) author>
% - \citeauthoronline
%     Produces <implicit (lowercase) author>
% - \apud[comments]{First}{Second}
%     Produces a double citation: (FIRST, YEAR apud SECOND, YEAR<, comments>)
% - \apudonline[comments]{First]{Second]
%     Produces a double citation: First (apud SECOND, YEAR<, comments>)
% - \Idem[comments]{Author}
%     Produces: Id., YEAR<, comments>
% - \Ibidem[comments]{Author}
%     Produces: Ibid.<, comments>
% - \opcit[comments]{Author}
%     Produces: AUTHOR, op. cit.<, comments>
% - \cfcite[comments]{Author}
%     Produces: Cf. AUTHOR, YEAR<, comments>
%
% - implementing `recuo' (bibindent style)
% - Macros for output sorted and compressed numerical citations
%     [9,2,3,1,4,11,7,10] becames [1--4,7,9--11]

% \bibliography{list of files .bib to be processed by bibTeX}
