% \section{The user interface}
%
% The content of \cs{caption} in longtables is usually centered to the content of the
% longtable itself.
% This is sufficient for centered longtables, but for left or right aligned longtables
% this results in captions moved into the left or right page margin.
%
% To solve this problem just include this package \emph{after} the \package{longtable}
% package\cite{longtable}, e.g.:
% \begin{quote}
%   |\usepackage{longtable,ltcaption}|
% \end{quote}
% Afterwards the captions of all longtables should be aligned as expected,
% even for not-centered longtables.
%
% \subsection{Further justification}
%
% \DescribeMacro{\LTcapskip}
% This length is controlling the skip between the caption and the contents
% below the caption (which is usually the longtable contents if you place
% the caption above the longtable), and it can be altered with
% |\setlength\LTcapskip{|\ldots|}|.
% When \thispackage\ is loaded it will be set to |\abovecaptionskip| which
% usually represents the skip between caption and contents in floating
% environments.
% (Without this package, the \package{longtable} package uses |\baselineskip| here.)
%
% \DescribeMacro{\LTcapleft}
% \DescribeMacro{\LTcapright}
% You can alter the centering of the caption box (of width |\LTcapwidth|)
% by setting the lengths |\LTcapleft| \& |\LTcapright| to appropriate values.
% These are set to |\fill| by default, just like the values |\LTleft| \& |\LTright|.
%
% \DescribeMacro{\LTcapmarginsfalse}
% Another option is the usage of the command |\LTcapmarginsfalse| which makes
% \thispackage\ using the values |\LTleft| \& |\LTright| instead of
% |\LTcapleft| \& |\LTcapright|.
%
% \emph{Note:}
% If \thispackage\ will be used with one of the \package{NTG} document
% classes\cite{NTGclasses}, |\CaptionLabelFont| \& |\CaptionTextFont| will
% not only be used for |figure| \& |table| captions, but for |longtable|
% captions as well.
%
% \emph{Note:}
% These lengths \& commands do not work when \thispackage\ is used with one
% of the \KOMAScript\ document classes \class{scrartcl}, \class{scrreprt}, or \class{scrbook}~\cite{KOMAScript},
% or used with the \class{memoir} document class~\cite{memoir}.
% The \KOMAScript\ resp.~\class{memoir} settings for captions are used instead.
% Same with the \package{caption} package which also uses its own options
% and settings.
%
% \subsection{Bonus features}
%
% \DescribeMacro{\LTcaptype}
% As a bonus feature this package patches the \package{longtable} package
% so |\LTcaptype| will be used internally instead of the fixed caption type
% `table'. So for example this code snipped:
% \begin{quote}
%   |\renewcommand\LTcaptype{figure}|\\
%   |\begin{longtable}{ll}|\\
%   |\caption{An example longtable}\\|\\
%   |  A & B \\|\\
%   |\end{longtable}|
% \end{quote}
% \pagebreak[3]
% will result in a longtable like this:
% \pagebreak[3]
% \setcounter{figure}{6}
% \begingroup
%   \renewcommand\LTcaptype{figure}
%   \begin{longtable}{l}
%   \caption{An example longtable}\\
%     \ldots \\
%   \end{longtable}
% \endgroup
%
% \DescribeEnv{longtable*}
% Another bonus feature is the addition of the environment |longtable*| which
% does not increment the |table| counter. (As a consequence, |\caption| is not
% available for such longtables, but |\caption*| still is.)
%
