%With this package you can create dummy text.
%Use \cmd{\blindtext} to get some text and
%\cmd{\Blindtext} to get a long text.
%With \cmd{\blinddocument} (or \cmd{\Blinddocument})
%you get complete dummy documents.
%
%Details can be found at \url{http://tex.lickert.net/packages/blindtext/index_en.html}.
%This File describes version \blindfileversion.
%
%\selectlanguage{ngerman}
%\em
%Mit diesem Paket kann man lange Texte erzeugen, ohne lange
%Texte einzugeben.
%Sinn ist die Erzeugung langer Beispieltexte, ohne den
%Quelltext lang zu machen.
%
%Details unter \url{http://tex.lickert.net/packages/blindtext/}.

% \subsection{Create Documents}
% \DescribeMacro{\blinddocument}
% \cmd{\blinddocument} create a document with sections,
% subsections\ldots and lists (\Lenv{itemize},
% \Lenv{enumerate} and \Lenv{description}).
%
% \DescribeMacro{\Blinddocument}
% \cmd{\Blinddocument} create a
% document with bigger sections, subsections\ldots and longer
% lists.\par
%
% The smallest document to check the look of a class would be:
% \begin{quote}
% \begin{verbatim}
% \documentclass{<class>}
% \usepackage{blindtext}
% \begin{document}
%     \blinddocument
% \end{document}
% \end{verbatim}
% \end{quote}
%
% If you want to have a table of contents you have two ways:
% \begin{enumerate}
%    \item use the package option 'toc'
%    \item Just add the |\tableofcontents|-command in your testdocument.
%  \end{enumerate}
%
% \subsection{Get some text}
% \DescribeMacro{\blindtext}
% \cmd{\blindtext}\oarg{x} create a text. The optional parameter defines a
% repetition. Default for the repetition is one and can be modified
% with \cmd{\setcounter}\marg{blindtext}\marg{1}.
%
% \DescribeMacro{\Blindtext}
% \cmd{\Blindtext}\oarg{x}\oarg{y} create $x$ paragraphs with the text of
% \cmd{\blindtext}. The first optional parameter defines a
% repetition of the paragraphs. Default for the repetition is five
% and can be modified with \cmd{\setcounter}\marg{Blindtext}\marg{5}. The
% second optional parameter is given to \cmd{\blindtext}.
%
% It is possible to add a start and end sequence for each paragraph.
%
% \DescribeMacro{\parstart}
% \DescribeMacro{\parend}
% The two macros \cmd{\parstart} and \cmd{\parend} define a
% starting and ending sequence for each paragraph in
% \cmd{\Blindtext}.
%
% \subsection{Get some lists}
% \DescribeMacro{\blindlist}
% \cmd{\blindlist}\marg{env}\oarg{x} create a list, the type is defined by the
% obligatory parameter. The optional parameter defines a repetition.
% Default for the repetition is five and can be modified with
% \cmd{\setcounter}\marg{blindlist}\marg{x}.
%
% \DescribeMacro{\blindlistlist}
%  \cmd{\blindlistlist}\oarg{level}\marg{env}\oarg{x} creates cascaded lists up to
%  level \verb|level|, the type is defined by the second obligatory
%  parameter. The optional parameter defines a repetition. Default is the
%  same like in \cmd{\blindlist}.
%
% \DescribeMacro{\Blindlist}
% \cmd{\Blindlist}\marg{env}\oarg{x} create a list with long texts.
% The optional parameter defines a
% repetition. Default for the repetition is five and can be modified
% with \cmd{\setcounter}\marg{blindlist}\marg{x}.
%
% \DescribeMacro{\blindlistoptional}
% \cmd{\blindlistoptional}\marg{env}\oarg{x} create a list with \cmd{\item}\oarg{}. The
% list is defined by the obligatory parameter. The optional
% parameter defines a repetition. Default for the repetition is five
% and can be modified with \cmd{\setcounter}\marg{blindlist}\marg{x}.
%
% \DescribeMacro{\Blindlistoptional}
% \cmd{\Blindlistoptional} create a list like
% \cmd{\blindlistoptional} with long texts.
%
% \DescribeMacro{\blinditemize}
% \DescribeMacro{\blindenumerate}
% \DescribeMacro{\blinddescription}
% The commands \cmd{\blinditemize}, \cmd{\blindenumerate} and \cmd{\blinddescription}
% are abbreviations for \cmd{\blindlist}\marg{itemize}, \cmd{\blindlist}\marg{enumerate}
% and \cmd{\blindlist}\marg{description}.
%
% \DescribeMacro{\Blinditemize}
% \DescribeMacro{\Blindenumerate}
% \DescribeMacro{\Blinddescription}
% The commands \cmd{\Blinditemize}, \cmd{\Blindenumerate} and \cmd{\Blinddescription}
% are abbreviations for \cmd{\Blindlist}\marg{itemize}, \cmd{\Blindlist}\marg{enumerate}
% and \cmd{\Blindlist}\marg{description}.
%
% \subsection{Get some math in the text}
% \marginpar{\hfill math}
% If you need a dummy text with math formula, you can add
% some math with the package option 'math'.
%
%\DescribeMacro{\blindmathpaper}
% |\blindmathpaper| build some text with formulas in between.
% This macro is used in |\blinddocument| if |\blindmathtrue| is set.
%
% If you need dummy text with and without math, you can (de)activate
% the math option with the following commands:
%
%\DescribeMacro{\blindmathtrue}
% With |\blindmathtrue| you set a flag, so the following blind text contains
% inline math.
%
%\DescribeMacro{\blindmathfalse}
% With |\blindmathfalse| you reset the flag for inline math
% inside the blind text.
