+
+The best is to install bearwear with the package manager of your texsystem.
+
+For manual installation compile the .ins file. This will create bearwear.sty and bearwear-doc.tex.
+Move bearwear.sty  in <texmf>/tex/latex/bearwear/ and update the filename
+database. Compile bearwear.dtx to get the documentation 
+ (it will need the extrated bearwear-doc.tex and all the graphics files). 
+
+
+
+## DESCRIPTION
+
+This package offers commands to create shirts for a tikzbear.
+
+## REQUIREMENTS
+It needs a recent version of pgf and tikzlings-bears.

+\section{Basic Usage}
+
+ The package is based on \TikZ{} and the main command should be used in a \texttt{tikzpicture} or -- as shown in some of the examples -- with \verb+\tikz+.
+
+ \subsection{The shirts}
+ The package provides a number of shirts for the bear, \bearwearkey{long sleeves} and \bearwearkey{round neckline} are the defaults:
+ \begin{tcblisting}{righthand width=6cm}
+ \tikz\bearwear % default
+    [long sleeves,
+     round neckline];
+ \tikz\bearwear
+   [t-shirt];
+ \tikz\bearwear
+   [muscle shirt];
+
+ \tikz\bearwear
+   [v-neckline];
+ \tikz\bearwear
+   [t-shirt,v-neckline];
+ \tikz\bearwear
+   [muscle shirt,v-neckline];
+  \end{tcblisting}
+
+ \subsection{Dressing the bear}
+
+ To dress the bear with the shirt, simply add the \verb+\bear+ command from the \bearwearkey{tikzlings-bears} package.
+
+ \begin{tcblisting}{before=\parindent0pt\nopagebreak}
+ \tikz{\bear;\bearwear[v-neckline];}
+ \tikz{\bear;\bearwear[muscle shirt];}
+  \end{tcblisting}
+
+ \subsection{Coloring the shirts}
+
+ The body and the arms of the shirts can be colored. They are three basic keys: \bearwearkey{leftarm}, \bearwearkey{rightarm} and \bearwearkey{body}, and two meta keys: \bearwearkey{arms} and \bearwearkey{shirt}.
+ Basically every option that would make sense in a \lstinline|\fill|  is allowed here.
+ Patterns e.g. would work too.
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear
+    [v-neckline,
+     leftarm=red,
+     rightarm=green,
+     body=blue];
+ \end{tcblisting}
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[arms=green];
+ \end{tcblisting}
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear
+    [shirt=
+      {shade,
+       top color=blue,
+       bottom color=red}];
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower,before=\parindent0pt\nopagebreak}
+   \bear;
+   \bearwear
+     [v-neckline,
+      shirt  =
+        {pattern=
+          horizontal lines light blue}];
+ \end{tcblisting}
+
+ \subsection{Additional patterns}
+
+ As seen in the last example patterns can be added instead of colors, but sometimes it makes sense to
+ add them on top to preserve a background color. For this the package provides special \texttt{pattern} keys:\\
+ \bearwearkey{leftarm pattern}, \bearwearkey{rightarm pattern}, \bearwearkey{arms pattern},
+ \bearwearkey{body pattern}, \bearwearkey{shirt pattern},
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear
+     [v-neckline,
+      shirt=red,
+      body pattern =
+       {pattern=
+         {Stars[points=6,
+          radius=0.5mm,distance=1.5mm]},
+        pattern color=yellow}];
+ \end{tcblisting}
+
+ \subsection{Decorations}
+
+ The \lstinline|deco| keys add their value to a \texttt{path picture} key. This can be used to place emblems or use graphics as pattern. To help with the placement two coordinates are
+ predefined: \bearwearkey{bearheart} and \bearwearkey{beartummy}.
+
+ \begin{tcblisting}{tikz lower}
+   \bear;
+   \bearwear[shirt deco =
+    {\fill[red] (beartummy) circle (1pt);
+     \fill[red] (bearheart) circle (1pt);}
+     ]
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[shirt deco =
+    {\node at (beartummy)
+     {\includegraphics[width=5cm]
+       {tartan3}};}]
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[body deco=
+    {\node at ([yshift=-1mm]bearheart)
+      {\includegraphics[width=0.3cm]
+        {flag}};}];
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[
+     shirt=Beige!80!black,
+     body deco=
+      {\node at ([yshift=-1mm]bearheart)
+       {\includegraphics[width=0.5cm]
+         {latex-project-logo}};}];
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[
+     shirt=HotPink,
+     body deco=
+      {\path  (bearheart)--++(0,-3mm)
+        pic{hippo};}];
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[
+    arms= DeepSkyBlue,
+    body deco =
+     {\node at ([yshift=-2mm]beartummy)
+       {\includegraphics[width=4cm]
+         {montblanc}};
+      \node[text=white,
+           font=\tiny\sffamily]
+        at ([yshift=1.95mm]beartummy)
+        {{Mont Blanc}};
+     }]
+ \end{tcblisting}
+
+ \subsection{Scaling}
+
+ Scaling works as expected, but don't forget that nodes in \TikZ{} normally don't scale if you don't use the \lstinline|transform shape| key:
+
+ \begin{tcblisting}{tikz lower,before=\parindent0pt\nopagebreak,}
+  \begin{scope}[scale=1.5]
+  \bear;
+  \bearwear[
+    arms= DeepSkyBlue,
+    body deco =
+     {\node at ([yshift=-2mm]beartummy)
+       {\includegraphics[width=4cm]
+         {montblanc}};
+      \node[text=white,
+           font=\tiny\sffamily]
+        at ([yshift=2mm]beartummy)
+        {{Mont Blanc}};
+     }]
+   \end{scope}
+ \end{tcblisting}
+
+ \subsection{Setting up defaults}
+
+ With \lstinline|\bearwearsetup| you can change the defaults:
+
+ \begin{tcblisting}{}
+ \bearwearsetup
+   {body=green!50!black,arms=green}
+ \tikz{\bear;\bearwear;}
+ \tikz{\bear;\bearwear;}
+ \end{tcblisting}
+ \section{The brains behind \texorpdfstring{\bearwearlogo{}}{BearWear}}
+ \includegraphics[width=3cm]{baer}
+ \begin{description}
+ \item[Ulrike]
+  Bär, your decision to create \bearwearlogo{} has come as a surprise to many. Did you expect this?
+  \item[Bär] Quite true, Ulrike. I am better known as an outdoor type
+  and the fashionistas didn't reckon with me at all.
+ \item[Ulrike] So, why did you take this step?
+ \item[Bär] There were quite a few reasons -- most importantly
+ my deeply felt desire to bring more justice to the world.
+ Look at the wonderful world of \TikZ ducks fashion, and even Marmots have come
+ far in the area of refinement. Why should \TikZ bears be left behind?
+ \item[Ulrike] You are also concerned with the more momentous issues of our day.
+ \item[Bär] Correct! My fashion line is the first ever to have practically
+ no negative influence on our environment. Manufacture and transportation
+ are ecologically neutral. In fact it's the first time in the
+ history of world economy that goods are produced without
+ the use of raw materials.
+ \item[Ulrike] You claim that \bearwearlogo{} will have a global impact.
+ \item[Bär] Yes, the issue of globalization is one which has been interesting
+  me for a long time. \bearwearlogo{} caters for the needs of \TikZ bears all
+  over the world. There is the Longshirt Line for those who live near the poles,
+  t-shirts for those in temperate regions and even a Muscle Shirt Line for the
+  bears of Australia.
+ \item[Ulrike] How about individuality?
+ \item[Bär] I am particularly proud that \bearwearlogo{} enables every single
+ bear to create his own personal shirt -- free of the dictates of the modern
+ Brummells. He may use my suggestions but he need not do so.
+ \item[Ulrike] Will you be seen wearing your own creations?
+ \item[Bär] Well Ulrike, I am afraid this is not very likely.
+ I have got this most beautiful fur and I'd hate to  cover it with artifical
+ patterns -- no matter how ravishing.
+ \item[Ulrike] One last question: what impulse got you moving towards
+ \bearwearlogo{}?
+ \item[Bär] The death of Karl Lagerfeld. Someone had to fill the void.

+%<*docu>
+\section{Basic Usage}
+
+ The package is based on \TikZ{} and the main command should be used in a \texttt{tikzpicture} or -- as shown in some of the examples -- with \verb+\tikz+.
+
+ \subsection{The shirts}
+ The package provides a number of shirts for the bear, \bearwearkey{long sleeves} and \bearwearkey{round neckline} are the defaults:
+ \begin{tcblisting}{righthand width=6cm}
+ \tikz\bearwear % default
+    [long sleeves,
+     round neckline];
+ \tikz\bearwear
+   [t-shirt];
+ \tikz\bearwear
+   [muscle shirt];
+
+ \tikz\bearwear
+   [v-neckline];
+ \tikz\bearwear
+   [t-shirt,v-neckline];
+ \tikz\bearwear
+   [muscle shirt,v-neckline];
+  \end{tcblisting}
+
+ \subsection{Dressing the bear}
+
+ To dress the bear with the shirt, simply add the \verb+\bear+ command from the \bearwearkey{tikzlings-bears} package.
+
+ \begin{tcblisting}{before=\parindent0pt\nopagebreak}
+ \tikz{\bear;\bearwear[v-neckline];}
+ \tikz{\bear;\bearwear[muscle shirt];}
+  \end{tcblisting}
+
+ \subsection{Coloring the shirts}
+
+ The body and the arms of the shirts can be colored. They are three basic keys: \bearwearkey{leftarm}, \bearwearkey{rightarm} and \bearwearkey{body}, and two meta keys: \bearwearkey{arms} and \bearwearkey{shirt}.
+ Basically every option that would make sense in a \lstinline|\fill|  is allowed here.
+ Patterns e.g. would work too.
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear
+    [v-neckline,
+     leftarm=red,
+     rightarm=green,
+     body=blue];
+ \end{tcblisting}
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[arms=green];
+ \end{tcblisting}
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear
+    [shirt=
+      {shade,
+       top color=blue,
+       bottom color=red}];
+ \end{tcblisting}
+
+
+
+ \begin{tcblisting}{tikz lower,before=\parindent0pt\nopagebreak}
+   \bear;
+   \bearwear
+     [v-neckline,
+      shirt  =
+        {pattern=
+          horizontal lines light blue}];
+ \end{tcblisting}
+
+ \subsection{Additional patterns}
+
+ As seen in the last example patterns can be added instead of colors, but sometimes it makes sense to
+ add them on top to preserve a background color. For this the package provides special \texttt{pattern} keys:\\
+ \bearwearkey{leftarm pattern}, \bearwearkey{rightarm pattern}, \bearwearkey{arms pattern},
+ \bearwearkey{body pattern}, \bearwearkey{shirt pattern},
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear
+     [v-neckline,
+      shirt=red,
+      body pattern =
+       {pattern=
+         {Stars[points=6,
+          radius=0.5mm,distance=1.5mm]},
+        pattern color=yellow}];
+ \end{tcblisting}
+
+ \subsection{Decorations}
+
+ The \lstinline|deco| keys add their value to a \texttt{path picture} key. This can be used to place emblems or use graphics as pattern. To help with the placement two coordinates are
+ predefined: \bearwearkey{bearheart} and \bearwearkey{beartummy}.
+
+ \begin{tcblisting}{tikz lower}
+   \bear;
+   \bearwear[shirt deco =
+    {\fill[red] (beartummy) circle (1pt);
+     \fill[red] (bearheart) circle (1pt);}
+     ]
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[shirt deco =
+    {\node at (beartummy)
+     {\includegraphics[width=5cm]
+       {tartan3}};}]
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[body deco=
+    {\node at ([yshift=-1mm]bearheart)
+      {\includegraphics[width=0.3cm]
+        {flag}};}];
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[
+     shirt=Beige!80!black,
+     body deco=
+      {\node at ([yshift=-1mm]bearheart)
+       {\includegraphics[width=0.5cm]
+         {latex-project-logo}};}];
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[
+     shirt=HotPink,
+     body deco=
+      {\path  (bearheart)--++(0,-3mm)
+        pic{hippo};}];
+ \end{tcblisting}
+
+ \begin{tcblisting}{tikz lower}
+  \bear;
+  \bearwear[
+    arms= DeepSkyBlue,
+    body deco =
+     {\node at ([yshift=-2mm]beartummy)
+       {\includegraphics[width=4cm]
+         {montblanc}};
+      \node[text=white,
+           font=\tiny\sffamily]
+        at ([yshift=1.95mm]beartummy)
+        {{Mont Blanc}};
+     }]
+ \end{tcblisting}
+
+ \subsection{Scaling}
+
+ Scaling works as expected, but don't forget that nodes in \TikZ{} normally don't scale if you don't use the \lstinline|transform shape| key:
+
+ \begin{tcblisting}{tikz lower,before=\parindent0pt\nopagebreak,}
+  \begin{scope}[scale=1.5]
+  \bear;
+  \bearwear[
+    arms= DeepSkyBlue,
+    body deco =
+     {\node at ([yshift=-2mm]beartummy)
+       {\includegraphics[width=4cm]
+         {montblanc}};
+      \node[text=white,
+           font=\tiny\sffamily]
+        at ([yshift=2mm]beartummy)
+        {{Mont Blanc}};
+     }]
+   \end{scope}
+ \end{tcblisting}
+
+ \subsection{Setting up defaults}
+
+ With \lstinline|\bearwearsetup| you can change the defaults:
+
+ \begin{tcblisting}{}
+ \bearwearsetup
+   {body=green!50!black,arms=green}
+ \tikz{\bear;\bearwear;}
+ \tikz{\bear;\bearwear;}
+ \end{tcblisting}
+ \section{The brains behind \texorpdfstring{\bearwearlogo{}}{BearWear}}
+ \includegraphics[width=3cm]{baer}
+ \begin{description}
+ \item[Ulrike]
+  Bär, your decision to create \bearwearlogo{} has come as a surprise to many. Did you expect this?
+  \item[Bär] Quite true, Ulrike. I am better known as an outdoor type
+  and the fashionistas didn't reckon with me at all.
+ \item[Ulrike] So, why did you take this step?
+ \item[Bär] There were quite a few reasons -- most importantly
+ my deeply felt desire to bring more justice to the world.
+ Look at the wonderful world of \TikZ ducks fashion, and even Marmots have come
+ far in the area of refinement. Why should \TikZ bears be left behind?
+ \item[Ulrike] You are also concerned with the more momentous issues of our day.
+ \item[Bär] Correct! My fashion line is the first ever to have practically
+ no negative influence on our environment. Manufacture and transportation
+ are ecologically neutral. In fact it's the first time in the
+ history of world economy that goods are produced without
+ the use of raw materials.
+ \item[Ulrike] You claim that \bearwearlogo{} will have a global impact.
+ \item[Bär] Yes, the issue of globalization is one which has been interesting
+  me for a long time. \bearwearlogo{} caters for the needs of \TikZ bears all
+  over the world. There is the Longshirt Line for those who live near the poles,
+  t-shirts for those in temperate regions and even a Muscle Shirt Line for the
+  bears of Australia.
+ \item[Ulrike] How about individuality?
+ \item[Bär] I am particularly proud that \bearwearlogo{} enables every single
+ bear to create his own personal shirt -- free of the dictates of the modern
+ Brummells. He may use my suggestions but he need not do so.
+ \item[Ulrike] Will you be seen wearing your own creations?
+ \item[Bär] Well Ulrike, I am afraid this is not very likely.
+ I have got this most beautiful fur and I'd hate to  cover it with artifical
+ patterns -- no matter how ravishing.
+ \item[Ulrike] One last question: what impulse got you moving towards
+ \bearwearlogo{}?
+ \item[Bär] The death of Karl Lagerfeld. Someone had to fill the void.
