% The package |etoolbox| provides the command
% |\AfterEndEnvironment| which creates a hook executed at a
% very late point inside the |\end| command. However, this
% hook is still located before |\ignorespaces|, which is
% too early to properly suppress the indention after an
% environment. Therefore another hook is now added to |\end|
% using |\patchcmd|. This new hook puts new code at the very
% end.

%
% \noindent This command implements the main principle
% behind this package. It checks whether it is followed by
% a paragraph. If so, the command |\par| is temporarily
% changed using |\everypar|, so that the following paragraph
% is not indented. Immediately afterwards, default paragraph
% behavior is restored with |\@restorepar| (from the \LaTeX{}
% base).
