%    line spacing commands and environments
%    Chapter and section: titles, page numbering, etc
%        This is a very delicated part. Let's give a flavour of what
%        happened. See comments in implementation for details.
%      redefining \chapter
%        - tests for determine begin of textual part and make changes at this
%          event.
%        - \pretextualchapter: a stared chapter in the pre-textual part
%        - ProximoForaDoSumario -> switches off \ABNTaddcontentsline.
%        - Marks: care is they are inserted by default or not.
%        - redefinig \@schapter: now \chapter* is almost equal to \chapter,
%          appart from the title display. It also includes an entry in TOC.
%        - \@part and \@spart redefined: font purposes.
%        - defined \ABNTstartsection: stared section with centralized titles
%           and inclusion in TOC.
%        - new \@dottedtoline for compleance with NBR 6027-1989
%        - \@makechapterhead and \@makeschapterheadredefined to fit
%          norms. Paying attention to capchap and fonts.
%        - redefined all \section like commands (apply last redefinitions
%          and font purposes)
%        - \anexo and \apendice -> apply old \appendix changes and
%          replaces \@chapter by \@anapchapter.


%    redefining important commands (those that set page marks, getting rid
%      of explicit \MakeUppercase)
%        \tableofcontents
%        \listoffigures
%        \listoftables

%    environment citado = citacao, for long quotations
%    pre-textual elements
%      Capa (cover) and Folha de rosto (face page): defining commands

% Revision 1.26  2003/10/13 09:40:01  gweber
% Passa a usar cvs-id.def para gerar informações sobre data e versão.
%
% Revision 1.25  2003/09/16 16:49:29  gweber
% Troca de \bibname por \refname o que equivale a trocar "Referêncas Bibliográficas" por

%
% Revision 1.24  2003/08/22 14:45:18  gweber
% Resolvido bug 178 que fazia o texto de \part aparecer duas vezes.
%
% Revision 1.23  2003/06/30 14:10:47  gweber
% Links criados com hyperref para apêndices e anexos não misturam mais com os links para capítulos comuns,
% resolvendo o bug #140.
%
% Revision 1.22  2003/05/30 10:39:19  gweber
% Alterações introduzidas em 0.7-beta.
%
% Revision 1.21.2.1  2003/05/30 10:16:07  gweber
% Correction of bug 137 which causes the class to fail when loading
% the package hyperref and using \tableofcontents.
% This also resolves partially bugs 82 and 51.
%
%
% Added in version 1.1 patch 1
%
% - fixed bug of undefined \ABNT<section name>mark, which shows twice the
%   section name (only for subsection, subsubsection, and paragraph)
%
% Added in version 1.1
%
% - Fixed bug of missing paragraphy after \chapter
% - \ProximoForaDoSumario has optional parameter to et page marks
% - Fixed bug of abscense of package setspace.
% - Added options `abntfigtabnum' and `normalfigtabnum' to deal with
%   figure and table counters.
% - Added abnt style for toc. Options `abnttoc' and
%   `normaltoc' were added.
% - Fixed bug of defining pagestyles only if non-noheader.
%
% Added in version 1 (finally)
%
% - Fixed mispelling on command \espaco.
% - Fixed "capsec" (not working before).
% - Added full support for Annex and Appendix, with several class options
%   and commands for customization.
% - Not using package "textcase" anymore, since there is a undesirable
%   extra space included with \MakeUppercase.
% - Fixed default options. Now "openright" is really default.
% - Now using feature of "setspace" to avoid extra spacing on display
%   math. No bugs if the version of setspace is not up to date.
% - Added \ProximoForaDoSumario, to avoid one to not include all \chapter*
%   if one wants to set diferently the title and contents of such chapters.
% - Fixed bug on \part toc entries (buggy extra space)
% - Now font size for \capter(*) is given by \ABNTchaptersize, preventing a
%   boring redefinition of \ABNTtocchapterfont.
% - Option paccomuns no longer default.
%
% Added in version 1 beta 3
%
% - Fixed bug in page marks for \section*{}.
% - "setspace" no longer require especific (new) version.
% - Added "no displayskip stretch" support offered by 'setspace' for better
%   aesthetic.
% - Added compatibility with "hyperref" package (no more incompatible
%   optional parameter on \chapter* -- hyperref redefines some commands)
% - Useless commands removed: \cabecalhoesq and \cabecalhodir.
%
% Added in version 1 beta 2
%
% - Correct figure and table counter.
% - Some support to "folha de apresentacao", including environment
%     \begin{folhadeapresentacao} e \assinatura{} (signature).
% - Fixed bug in pnumplain and headers.
% - Fixed bug in page marks for \@schapter.
%
% Added in version 1 beta
%
%   Total reformulation of the class! The main added feature are:
% - Good machanism for "Folha de Rosto" (face page) added.
% - Page numbering squemes according to the norms.
% - Right page headings.
% - Correct section titles.
% - Several options added.
% - Features removed, like margin care
% ...too many changes to list. Just like a "new" class.
%
% Added in version 0.4.3
%
% - Stupid but severe bug on \listoffigures and \listoftables
%     left from previous version finally removed
% - Bug fixes in theindex and thebibliography
% - Redefinition of \cleardoublepage (empty page => page style empty)
% - This `list of changes' added
%
% Added in version 0.4.2
%
% - Added \StarChaptersInTOC, \StarChaptersNotInTOC to differenciate  
%    from "standard" (old) stared chapters like \tableofcontents,
%    \listoffigures, \listoftables, thebibliography and theindex.
% - Huge bugs in commands or environments \tableofcontents, \listoffigures,
%    \listoftables, thebibliography and theindex fixed.
% - Command \SpAcEs changed to \spABNT (more reliable than before)
%
% Added in version 0.4.1
%
% - Extract forgotten debug command
% - Fix conflict (\Sp command) in final messagem, creating \SpAcEs (and
%     hoping nobody made it before)
%

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%    Chapter title page style
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% Redefining \chapter and \part. The changes are
%  - \chapteritlepagestyle instead of explict plain page style
%  - \ABNTchaptermark instead of \chaptermark (must be before
%       \addcontentsline !!!)
% - several commands were replaced by abntversions due to nuances of the
%   norms :-( it can create several uncompatibilities with packages that
%   change explictily these important commands, although I have tried very
%   hard to make as less damage on compatibility as possible. As a result
%   of this, package hyperref is totally broken with abnt.cls.

%%%%%%%%%%%%%%%%%%%%%%   Special definitions   %%%%%%%%%%%%%%%%%%%%
% What is going on here?
%   
%  This class supports auto include in toc for both \chapter* and
%  \section* (and similars). As we know, the command \chapter admits an
%  optional argument, which goes to the toc and the marks, if it's present
%  (otherwise the main parameter of \chapter is used in toc and marks also.)
%  
%  To allow exactly the same mechanism for \chapter and \chapter*, \section
%  and \section*, \subsection and \subsection*, etc, I had to define
%  similar commands to some important core commands in LaTeX, like \secdef
%  (we make a new one to avoid conflicts with other packages) and
%  \@startsection (I make a new one too).
%
%  Now, \ABNTstartsection, appart from make the stared version of a
%  section-like command to include the title in toc (if a boolean is set to
%  true), the title is centered for stared form.
%
%  Now, \chapter* and \part* are almost equal to \chapter and \part
%
%  The origin of this material are the files 
%     $texmfDIR/tex/latex/base/latex.ltx  (codigo fonte do LaTeX)
%     $texmfDIR/tex/latex/base/report.cls (classe standard)

% From the definition of \secdef -> stared version now admits optional
% param (after bug with hyperref, it was no longer used.)
