% We use |\DeclarePairedDelimiters| to generate all kind of bracket
% expressions of variable size as used e.g. in differential
% geometry. This has the big advantage that one has two options to set
% the size of the brackets: either with an explicit optional argument
% |\big|, \ldots, |\Bigg|, |\vast|, or |\Vast| like
% \begin{quote}
% 	|\Schouten[\vast]{X, Y}|: $\Schouten[\vast]{X, Y}$
% \end{quote}
% or you can use the *-version which produces automatic sizes via
% |\left| and |\right|.
% \begin{quote}
%     |\abs*{\lim\limits_{n\to\infty} b_n}|
%     yields
%     $\abs*{\lim\limits_{n\to\infty} b_n}$
% \end{quote}
% Note, however, that this will typically result in sub-optimal
% spacing. Also, the brackets turn out to be typically too large.
%
%
% Note that using the bracket constructions with
% |\DeclarePairedDelimiters| gives typically much better spacing than
% doing things by hand:
% \DeleteShortVerb{\|}
% \begin{quote}
%     good \verb|\abs{\det(A)}|:
%     $\abs{\det(A)}$
%     \qquad
%     bad \verb+|\det(A)|+:
%     $|\det(A)|$

% In many formulas one needs large delimiters typically ranging from
% |\big| to |\Bigg|. However, in very large formula constructions even
% that is not enough. To have a systematic enlargement the following
% delimiters sizes are introduced: |\vast| and |\Vast| together with
% the corresponding helper macros |\vastl|, |\vastr|, |\vastm|,
% |\Vastl|, |\Vastr|, and |\Vastm| needed to define pairs of
% delimiters.  They allow to produce large (pairs of) delimiters,
% always provided that the corresponding font has the symbols in the
% correct size.
%
%
% The following commands allow for an option size argument:
% \begin{itemize}
% \item Absolute value |\abs|
% \item Generic norm |\norm|
% \item Supremum norm |\supnorm|
% \item Essential supremum norm |\essupnorm|
% \item Dirac ket |\ket|
% \item Dirac bra |\bra|
% \item Dirac ketbra |\ketbra|
% \item Dirac braket |\braket|
% \item Schouten bracket |\Schouten|
% \item Nijenhuis-Richardson bracket |\NRbracket|
% \item Frölicher-Nijenhuis bracket |\FNbracket|
% \item Courant bracket |\Courant|
% \item Dorfman bracket |\Dorfman|
% \item Generic scalar product |\SP|
% \item Generic inner product with decorations |\IP|
% \item Restriction of a map |\at|
% \item Étalé space of a presheaf |\etale|
