+% \begin{abstract}
+% \centering
+% This package offers the command
+% |\Declare|\-|Floating|\-|Environment| for defining new floating environments
+% which behave like |figure| and |table|.
+% \end{abstract}
+% 
+% \tableofcontents
+%
+% \clearpage
+% \section{Loading the package}
+%
+% First of all you need to include this package into your document with
+% \begin{quote}
+%   |\usepackage|\oarg{options}|{newfloat}|
+% \end{quote}
+% where \meta{options} are one or more of
+% \begin{quote}\begin{tabular}{r@{\,}l}
+%   |within=| & \meta{``within'' counter} \emph{or} \texttt{none}\quad\\
+%   |chapterlistsgap=| & \meta{value}~\footnotemark[1]
+% \end{tabular}\end{quote}
+%
+% The ``within'' counter specifies the counter which will be used to reset
+% the counter of the floating environments |figure| and |table| .
+% (Furthermore this setting will be used as default setting for
+% |\Declare|\-|Floating|\-|Environment|.)
+%
+% So for example |within=chapter| will give you a numbering scheme
+% \meta{chapter}.\meta{x} for floating environments,
+% while |within=section| will give you a numbering scheme
+% \meta{chapter}.\meta{section}.\meta{x}, or \meta{section}.\meta{x}
+% if the document class does not offer |\chapter|.
+% |within=none| will result in a continuous numbering throughout the document,
+% i.e.~the numbering scheme will be simply \meta{x}.
+%
+% The option |chapterlistsgap=|\meta{value} sets the amount of the
+% vertical gap inserted into the ``List of Figure'', ``List of Tables'',
+% and all lists created with |\Declare|\-|Floating|\-|Environment|
+% when a new chapter will be started.
+% The default value is |10pt|.
+% (This option will only be available if the document class used offer
+% the usage of chapters, e.g.~the |book| or |report| document class.)
+%
+% \pagebreak[3]
+% Both options can be changed later on, too, by using the command
+% \begin{quote}
+% |\newfloatsetup|\meta{options}\quad,
+% \end{quote}
+%
+% \pagebreak[3]
+% \section{\cs{DeclareFloatingEnvironment}}
+%
+% After loading \thispackage\ you can define your own floating environments with
+% \begin{quote}
+% \iffalse
+% \setlength{\leftmargin}{6cm}
+% \fi
+%  |\DeclareFloatingEnvironment|\oarg{options}\marg{type}%
+% \iffalse
+%   \oarg{name}\oarg{list name}
+% \fi
+% \end{quote}
+% where \meta{options} are one or more of
+% \begin{quote}\begin{tabular}{r@{\,}l}
+%   |fileext=| & \meta{file extension}\\
+%   |listname=| & \meta{list name}\\
+%   |name=| & \meta{prosa name}\\
+%   |placement=| & \meta{combination of \,\purett{htbp}}\\
+%   |within=| & \meta{``within'' counter} \emph{or} \texttt{none}\\
+%   |chapterlistsgaps=| & \texttt{on} \emph{or} \texttt{off}~\footnotemark[1]
+% \end{tabular}\end{quote}
+% \footnotetext[1]{Please note that although \thispackage\ tries hard to offer this
+% option it may not be available or is working incorrectly in cooperation with
+% your document class since there is no standard interface which we could use
+% for that purpose. Therefore we have to try to patch the \cs{chapter} command,
+% and if this fails, we try to patch \cs{addtocontents} (in an unusual way) instead.}
+%
+% If no \meta{options} are given,
+% ``lo\meta{type}'' will be used as \meta{file extension} for the list,
+% ``List of \meta{name}s'' as \meta{list name}.
+% ``\meta{name}'' as \meta{name} (but with the first letter capitalized),
+% ``|tbp|'' as \meta{placement} specifier,
+% and ``|chapter|'' resp. ``|none|'' as \meta{``within'' counter},
+% i.e., the counter which resets the numbering.
+%
+% The default value of the |chapterlistsgaps=| option depends on the
+% ``within'' setting, it is set to |on| if |chapter| or |section| is selected,
+% otherwise it is set to |off|.
+% (This option will only be available if the document class used offer
+% the usage of chapters, e.g.~the |book| or |report| document class.)
+%
+% The list will be typeset using the command |\list|\-|of|\meta{type}|s|
+% resp.~|\list|\-|of|\meta{type}|es|,
+% analogous to |\list|\-|of|\-|figures| and |\list|\-|of|\-|tables|.
+%
+% If the \package{fltpage} package is loaded, an environment called
+% |FP|\meta{type} will be defined additionally, same for |sideways|\meta{type}
+% (\package{rotating} package), |SC|\meta{type} (\package{sidecap} package),
+% and |wrap|\meta{type} (\package{wrapfig} package).
+% 
+% \bigskip
+% 
+% \pagebreak[3]
+% So for example
+% \begin{quote}
+%   |\DeclareFloatingEnvironment{diagram}|
+% \end{quote}
+% will define a new floating environment called |diagram|,
+% the list will be stored in a file with the extension |lodiagram|, the name
+% (used for the caption) will be ``Diagram'' and the list name
+% ``List of Diagrams''.
+% The list could be typeset with |\list|\-|of|\-|diagrams|.
+% Dependent on which packages are loaded, the environments |FP|\-|diagram|,
+% |sideways|\-|diagram|, |SC|\-|diagram|, and |wrap|\-|diagram| will be defined additionally.
+%
+% \pagebreak[3]
+% Another example:
+% \begin{quote}
+%   |\DeclareFloatingEnvironment[|\\
+%   |  fileext=lox,|\\
+%   |  listname={List of Matrixes},|\\
+%   |  name=Matrix,|\\
+%   |  placement=p,|\\
+%   |  within=section,|\\
+%   |  chapterlistsgaps=off,|\\
+%   |  ]{matrix}|
+% \end{quote}
+% will define a new floating environment called |matrix| with the given settings.
+% Please note that names which contain spaces needs to be enclosed in curly braces.
+%
+% \pagebreak[3]
+% \section{\cs{SetupFloatingEnvironment}}
+%
+% While |\DeclareFloatingEnvironment| will create new floating environments,
+% \begin{quote}
+% |\SetupFloatingEnvironment|\marg{floating environment}\marg{options}
+% \end{quote}
+% will change the settings of existing ones, i.e. either |figure| or |table|,
+% or a one created with |\Declare|\-|Floating|\-|Environment|,
+% or a one created with |\new|\-|float| offered by the \package{float} package,
+% or a one created with |\new|\-|float| offered by the \package{memoir} document class,
+% or a one created with |\Declare|\-|New|\-|Float|\-|Type| offered by the \package{floatrow} package,
+% or \ldots
+%
+% The \meta{options} are the same as the options for
+% |\Declare|\-|Floating|\-|Environment|,
+% but one should avoid changing the file extension
+% of existing floating environments,
+% i.e.~using the |fileext=| option within |\Setup|\-|Floating|\-|Environment|
+% is usually a very bad idea.
+%
+% \bigskip
+%
+% \pagebreak[3]
+% An example:
+% \begin{quote}
+%   |\SetupFloatingEnvironment{lstlisting}{chapterlistsgaps=off}|
+% \end{quote}
+% will switch off the chapter lists gaps for |lstlisting| environments
+% offered by the \package{listings} package.
+%
+% \pagebreak[3]
+% \section{\cs{ForEachFloatingEnvironment}}
+%
+% \begin{quote}
+%  |\ForEachFloatingEnvironment|\marg{code with \#1}
+% \end{quote}
+% will execute the given \meta{code} for all known floating environments,
+% and for ones defined with |\Declare|\-|Floating|\-|Environment| later on.
+%
+% \pagebreak[3]
+% So for example the \package{subcaption} packages uses
+% \begin{quote}
+%  |\ForEachFloatingEnvironment{\DeclareCaptionSubType{#1}}|
+% \end{quote}
+% for initializing itself for all floating environments which are
+% known to \thispackage.
+%
+% \medskip
+%
+% There is also a starred variant |\For|\-|Each|\-|Floating|\-|Environment*|
+% which will execute the given code for already existing floating environments
+% only, i.e.~no hook will be placed inside |\Declare|\-|Floating|\-|Environment|.
+%
+% \pagebreak[3]
+% An example:
+% \begin{quote}
+%  |\ForEachFloatingEnvironment*{\typeout{#1}}|
+% \end{quote}
+% will typeout the names of all already known floating environments to the terminal
+% and log file.
+%
+% \pagebreak[3]
+% \section{\cs{PrepareListOf}}
+%
+% Unfortunately there is no standardized way of typesetting and customizing
+% lists of floating environments, i.e.~every document class offers it's own stuff here,
+% and there are plenty of \LaTeXe\ packages for this purpose.
+%
+% \pagebreak[3]
+% For that reason the \thispackage\ simply typesets the lists of newly
+% defined floating environments as ``List of Figure'' internally (using |\list|\-|of|\-|figure|)
+% but using a different list (the right one, of course) and using a different list name,
+% the one you have specified with either |\Declare|\-|Floating|\-|Environment| or
+% |\Setup|\-|Floating|\-|Environment|.\footnote{Please note that this is not the
+% fact when using a \KOMAScript\ document class, not \cs{listoffigure} but \cs{listoftoc}
+% will be used here, and therefore no problems should occur.}
+%
+% \pagebreak[3]
+% While this usually results in the same layout as the ``List of Figure'' and
+% is sufficient for most cases, there are some cases where this might
+% lead to an unwanted side effect.
+%
+% \pagebreak[3]
+% Therefore the \thispackage\ offers
+% \begin{quote}
+%  |\PrepareListOf|\marg{floating environment}\marg{code}
+% \end{quote}
+% which will execute the given \meta{code} right before actually typesetting the list
+% with |\list|\-|of|\-|figures| internally.
+%
+% \pagebreak[3]
+% One example:
+% \begin{quote}
+%   |\PrepareListOf{diagram}{%|\\
+%   |  \renewcommand{\cftfigpresnum}{Diagram~}}|
+% \end{quote}
+% will change the part typeset in front of the diagram number within the
+% ``List of Diagrams'' when using the \package{tocloft} package~\cite{tocloft}.
+% Without the code above you will get the part defined for figures instead.
+%
+% \pagebreak[3]
+% However, when dealing with the \package{tocloft} package it's a better
+% idea not to use |\Prepare|\-|List|\-|Of| but the customization facilities of that package
+% instead, e.g.:
+% \begin{quote}
+%   |\documentclass{book}|\\
+%   \ldots\\
+%   |\usepackage{newfloat,tocloft}|\\
+%   |\newlistof{diagram}{lod}{List of Diagrams}|\\
+%   |\DeclareFloatingEnvironment[name=Diagram,fileext=lod]{diagram}|\\
+%   |      % Note: Due of a bug in tocloft the file extension|\\
+%   |      % must be repeated at \DeclareFloatingEnvironment,|\\
+%   |      % otherwise you will get an empty list.|\\
+%   ||\\
+%   |% Customize `List of Figures'|\\
+%   |\renewcommand{\cftfigpresnum}{Figure~}|\\
+%   |\setlength{\cftfignumwidth}{2cm}|\\
+%   ||\\
+%   |% Customize `List of Diagrams'|\\
+%   |\renewcommand{\cftdiagrampresnum}{Diagram~}|\\
+%   |\setlength{\cftdiagramnumwidth}{2cm}|\\
+%   ||\\
+%   \ldots\\
+%   ||\\
+%   |\begin{document}|\\
+%   \ldots\\
+%   |\listoffigures|\\
+%   |\listofdiagrams|\\
+%   \ldots\\
+%   |\end{document}|
+% \end{quote}
+%
+% \iffalse
+% \pagebreak[3]
+% \section{For \LaTeX{} package authors}
+%
+% |\For|\-|Each|\-|Floating|\-|Environment| without \package{newfloat} package:
+% \begin{quote}
+%   |\newcommand\mypackage@foreachfloat[1]{%|\\
+%   |  \@ifundefined{ForEachFloatingEnvironment}%|\\
+%   |    {\def\@elt##1{#1}%|\\
+%   |      \@ifundefined{c@figure}\@gobble\@elt{figure}%|\\

+%   |  \@tempa}|\\
+%   |\providecommand*\newfloat@hook[1]{}|
+% \end{quote}
+%
+% \pagebreak[3]
+% Adding environment to list of floating environments:
+% \begin{quote}
+%   |\SetupFloatingEnvironment|\marg{environment}|{}|
+% \end{quote}
+% or (without \package{newfloat} package loaded):
