% This package offers the command
% |\Declare|\-|Floating|\-|Environment| for defining new floating environments
% which behave like |figure| and |table|.

% \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}\\
%   |autorefname=| & \meta{name used in \cs{autoref} offered by \pkg{hyperref}}\\
%   |legendname=| & \meta{name used in \cs{legend} offered by \cls{memoir}}\\
%   |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}, \meta{autoref name}, and \meta{legend 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 \pkg{fltpage} package is loaded, an environment called
% |FP|\meta{type} will be defined additionally, same for |sideways|\meta{type}
% (\pkg{rotating} package), |SC|\meta{type} (\pkg{sidecap} package),
% and |wrap|\meta{type} (\pkg{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|\\
%   |  ]{matrixx}|
% \end{quote}
% will define a new floating environment called |matrixx| 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 \pkg{float} package,
% or a one created with |\new|\-|float| offered by the \pkg{memoir} document class,
% or a one created with |\Declare|\-|New|\-|Float|\-|Type| offered by the \pkg{floatrow} package,
% or a one created by a document class or any other package.
%
% 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 \pkg{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 \pkg{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 \pkg{tocloft} package~\cite{tocloft}.
% Without the code above you will get the part defined for figures instead.
%
% \pagebreak[3]
% However, when dealing with the \pkg{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}
%
% \pagebreak[3]
% \section{Multi-language support}
%
% The options \opt{name=} etc.~will set names for the current language only.
% If support for multiple languages is needed, the command |\addto\captions|\meta{language}
% offered by the \pkg{babel} package needs to be used to set names for all the different languages.
%
% These are the corresponding command names:
%
% \nobreak\medskip\nobreak\noindent
% \begin{minipage}{\linewidth}
%   \centering
%   \begin{tabular}{lll}
%     Option             & Command                      & Description \\
%   \hline
%     \opt{listname=}    & |\list|\meta{float}|name|    & Heading of the list \\
%     \opt{name=}        & |\|\meta{float}|name|        & Name used in |\caption| \\
%     \opt{autorefname=} & |\|\meta{float}|autorefname| & Name used in |\autoref| \\
%     \opt{legendname=}  & |\fleg|\meta{float}          & Name used in |\legend| \\
%   \end{tabular}
% \end{minipage}
%
% \medskip
%
% \pagebreak[3]
% Example code:
% \nobreak\begin{quote}
%   |\documentclass{book}|\\
%   \ldots\\
%   |\usepackage[T1]{fontenc}|\\
%   |\usepackage[english,french,german]{babel}|\\
%   \ldots\\
%   |\usepackage{newfloat}|\\
%   |\DeclareFloatingEnvironment{diagram}|\\
%   |% Set names for the English language|\\
%   |\addto\captionsenglish{%|\\
%   |  \renewcommand\diagramname{Diagram}%|\\
%   |  \renewcommand\listdiagramname{List of Diagrams}%|\\

%   |% Set names for the French language|\\
%   |\addto\captionsfrench{%|\\
%   |  \renewcommand\diagramname{Diagramme}%|\\
%   |  \renewcommand\listdiagramname{Liste des diagrammes}%|\\
%   |}|\\
%   |% Set names for the German language|\\
%   |\addto\captionsgerman{%|\\
%   |  \renewcommand\diagramname{Diagramm}%|\\
%   |  \renewcommand\listdiagramname{Liste der Diagramme}%|\\
%   |}|\\
%   \ldots
% \end{quote}
%
% \pagebreak[3]
% \emph{Note:}
% As default the names for |\autoref| and |\legend| point to the one used for captions,
% so these names only need to be set if they should differ from it.
%
% \pagebreak[3]
% \section{Important notes for \LaTeX\ document class maintainers}
%
% If you are a maintainer of a \LaTeX\ document class and want to support this package
% you could tell this package to keep its fingers from your definition of |\chapter| by defining
% |\new|\-|float@dont@patch@chapter| to anything. (The content of the definition does not matter
% since the \pkg{newfloat} package only checks if this macro is defined or not.)
%
% If |\new|\-|float@dont@patch@chapter| is defined, the \pkg{newfloat} package does not try to patch
% |\chapter| but assumes that |\@add|\-|chapter|\-|lists|\-|gaps| is already used by the document class inside
% its definition of |\chapter|, so it only needs to re-define |\@add|\-|chapter|\-|lists|\-|gaps|
% to use the settings configured by |\De|\-|clare|\-|Float|\-|ing|\-|En|\-|vi|\-|ron|\-|ment|
% or |\Setup|\-|Float|\-|ing|\-|En|\-|vi|\-|ron|\-|ment|.
