%% This requires extensive explanation.
%%
%% Defining the command that displays the total number of pages requires to know
%% if hyperref is loaded or not, because it relies on \if-commands that do not
%% exist unless hyperref is loaded.
%%   But hyperref must be loaded by the user, not by gradu2, because hyperref
%% overwrites definitions made in many packages. The user may use such
%% packages, therefore hyperref must be loaded *after* these packages. In
%% addition, hyperref must be loaded before packages based on the float package,
%% because the latter is incompatible with hyperref.
%% gradu2 therefore expects the user to potentially load hyperref, and if it is
%% the case, it defines \TotPages@putlabel just before \begin{document}. This
%% could not be done with \AtBeginDocument, because hyperref also uses
%% \AtBeginDocument extensively, and gradu2' \AtBeginDocument{\def\@schapter...}
%% would have been executed *before* hyperref is loaded (\begin{document} hooks
%% are executed in the same order they are defined, and gradu2 would define its
%% hook before hyperref defines its ones).  Defining a hook in a hook i.e.,
%% \AtBeginDocument{\AtBeginDocument{\def\whatever}} does not work, gradu2
%% therefore needs to define its own hook, independently from the normal
%% \begin{document} hooks. The proper way of doing so would be to redefine
%% \document, but for some obscure reason, this does not work. The working
%% solution consists in redefining \begin and check if it is \begin{document}
%% (and then execute gradu2' own hook before actually executing
%% \begin{document}) or \begin{sometingelse} (then do nothing special).
%%   gradu2' own hook is one \AtBeginDocument that puts its own commands after every others
%% (defining \TotPages@putlabel, then calling \maketitle).
