%% Revision 1.42 2003/07/23 12:06:01 gweber
%% O comando apply.title.command agora atua sobre todas as ocorrências de title, mas
%% não sobre campos title que estão vazios.
%%
%% Revision 1.41 2003/07/22 16:26:02 gweber
%% Adicionada a opção abnt-title-command. Com esta opção pode-se definir o comando
%% \bibtextitlecommand que permite formatações especiais no titulo.
%%
%% Revision 1.40 2003/06/05 14:34:05 gweber
%% Introduzido filtro.url.tex e filtro.url.html, a função do primeiro é alterar uma url de tal maneira
%% que que o TeX possa processá-la sem problemas. A do segundo é fazer a mesma coisa
%% para a url que é passada para html ou hyperref.
%%
%% Revision 1.39 2003/06/04 13:18:07 gweber
%% Introduzidas as opções hyperref para abnt.url.package com isso os campos url são formatados agora como hyperlinks ativos.
%% Também foram acrescentadas a opção abnt.doi que permite selecionar o tratamento que recebe uma url começada com doi:
%%
%% Revision 1.38 2003/04/08 00:39:39 gweber
%% Implementada a entrada @hidden que gera um \hiddenbibitem (só alf),
%% ou seja uma entrada que não aparece na lista de referências e que pode ser
%% usada com o comando \apud e \apudonline.
%%
%% Revision 1.37 2003/04/01 19:34:47 gweber
%% consertado bug de ordenação alfabética, agora a ordenação em sort.format.names é igual a de format.names
%%
%% Revision 1.36 2003/03/25 14:06:20 gweber
%% Inicio da adaptação para ISO 690:1987.
%% Acrescentada a opção iso-author-punctuation cuja opção
%% void gera iniciais juntas e sem ponto.
%%
%% Revision 1.35 2003/03/22 22:59:13 gweber
%% abnt-nbr10520 foi substituído por abnt-cite-style.
%% A função recompose.name recompõe um nome complicado, mas a função
%% ainda é experimental e não está sendo usada no momento. Mesmo
%% porque há nomes que o próprio bibtex tem problemas para tratar.
%% A função presort for modificada de modo a poder manter o SORT em
%% abnt-num sem realmente ordenar alfabeticamente.
