% \begin{abstract}\noindent
% The \pkg{mwe} CTAN package comes with a small \LaTeX\ package which loads
% packages commonly used to create minimal working examples (MWEs)
% and with a collection of dummy images. The idea is that this images
% are installed in the \texttt{TEXMF} tree in a way where they are accessible
% by any document. Then MWEs with images can be shared by multiple users
% without the need of image replacement code or the \texttt{dummy} option of \texttt{graphicx}.
% \end{abstract}
%
% \section{Introduction and Motivation}
% \LaTeX\ has a large online-community and people can find a lot of help from other users
% on places like
% \href{https://groups.google.com/forum/?fromgroups#!forum/comp.text.tex}{\texttt{comp.text.tex}}
% or \url{http://tex.stackexchange.com/}.
% In many cases the user with the problem is required to post a code example which shows
% the use-case, but nothing unrelated, and should be compilable by other people without extra effort.
% Such an example is often called a \emph{minimal working example} (MWE), or sometimes only \emph{minimal example}.
% Users can use this example document to test if the issue also occurs in their \LaTeX\ installation and
% easily implement and test solutions. If a solution is found the modified example can be posted back to the original
% user. For general questions like "How to do X", answers often create an example document by themselves.
%
% There are some packages which are very useful for MWEs (and mostly only for these), like the \pkg{lipsum}
% and \pkg{blindtext} packages. Both produce dummy text in the document which is required to produce realistic scenarios
% for e.g.\ float placement etc. This frees the user from typing or copying larger dummy texts by himself,
% which would also increase the size of the example and make it less readable.
% The \pkg{mwe} package loads such packages and allows for a further reduction of the MWE document size.
%
% A problem with sharing MWEs appears if image files are included in the document (e.g.\ \Macro\includegraphics,
% \env{figure} environments etc.). Often the image is replaced with a replacement code like
% \Macro\rule{<width>}{<height>} or the \texttt{demo} option of \pkg{graphicx} is used to replace the image with an
% empty frame without trying to read the given image file.
% Both of these methods are a little cumbersome and have other issues. For once, an explanation for new users must be
% added to replace the code with a real \Macro\includegraphics or to remove the \texttt{demo} option for their final
% document. Another issue might arise when the example requires specific image options like scaling or cropping,
% which might not be easily and completely be replicated with these replacements.
% Also, the compiled result will look less than a normal document with real images.
%
% To overcome these drawbacks several real dummy images with different sizes, ratios and formats are provided with
% this package. Once installed in the correct directory in the \texttt{TEXMF} tree they will be available to all
% documents. This way a user can compile any MWE given to him by another person
% which uses these image files without requiring code replacements or sharing images. The \pkg{mwe}, which loads
% \pkg{graphicx}, can be used to minimise the preamble, but is not required to be loaded in order to use the images.
%
% It should be noted that the main contribution of this CTAN package is, at least at the moment, the provided demo/test image files.
% The \pkg{mwe} \LaTeX\ package is (in his current form) just an addition.
%
% \section{Usage}
% The provided image files can be included as normal using i.e.\ using the \pkg{graphicx} package and its
% \Macro\includegraphics[<options>]{<filename>} macro.
% They are also provided in source code form (\texttt{.tex} files) and can be included in a document
% using \Macro\input{<filename>}. They require the \pkg{tikz} package to be loaded.
% For this to work it is important that the images are located at the indented position in the \texttt{TEXMF} tree as
% described in section~\ref{sec:installation}.
%
% The \pkg{mwe} can be loaded in the preamble of a MWE and loads often used packages.
% At this moment these are only \pkg{graphicx}, \pkg{lipsum} and \pkg{blindtext}, while the last two are only
% loaded if they are installed. The package is not required for using the image files.
% If the package is loaded it will change the graphic extension list so that PDF files are used first for formats which
% support PDF images. Also \Macro\graphicspath{{example-}} is used to allow to shorten the file names to `|image..|'
% instead of the full `|example-image...|'.
%
% Some MWE might even be better off not to use the package if specific side-effect between packages is tested.

%
% \section{Installation}\label{sec:installation}
% The \pkg{mwe} package has due to its nature a little uncommon installation requirements.
% While the normal package files are installed as normal, a variety of image files
% are installed in the \texttt{tex/latex/mwe/} folder, so that they can be accessed from
% every (MWE) document.
%
% Multiple binary images are included which can't be build from the DTX alone
% without extra conversion tools.  A TDS ZIP file which only needs to be unzipped
% over the TEXMF is also provided.  This is the preferred way to install this
% package for end users and distribution maintainers.  If a manual build is wanted
% change all occurrences of `|nostandalone|' to `|standalone|' in the DTX file.
% Compile all extracted TEX files with |pdflatex| and convert these files from PDF
% to PNG and JPG. Compile again with |latex| and |dvips| to create the EPS files
% (rename the PS to EPS).

% \section{Provided Images}
% The following images are provided by \pkg{mwe}.
% If the \pkg{mwe} \LaTeX\ package is loaded the PDF version will be used instead of the PNG version
% and the `|example-|' part of the filename may be skipped.
%
% \subsection{Normal Images}
% The following images are meant as dummy replacements for real images.
% They are provided as PDF, JPG, PNG and EPS formats in order to cover every possible use-case.
% They are also provides as TEX files holding the source code. The \pkg{tikz} package must be loaded
% in order to use them in a document. These source files originally use the \cls{standalone} class and a preamble,
% but these lines have been commented out, in order to not require the \pkg{standalone} package in order to \Macro\input
% them into a MWE or test document.

% \subsection{Test images}
% The following images are intended for demonstrations of some image manipulation features.
% Their grid nature will make cropping effects very visible.
% These images are provided with sizes both in TeX points (1pt=1/72.27in) and PostScript/PDF points (1pt=1/72in).
% The pt version will produce more exact results if inserted in source form in a \LaTeX document, while the bp version
% results in nice integer PDF sizes. The difference is not meaningful for normal MWEs but can be significant if these files
% are used to demonstrate scaling features.
