 Installation:
 -------------
 In order to use gastex you only need two files:
-- gastex.sty which contains the definition of all the LaTeX macros (this file
-could be in your working folder or where other .sty files are).
-- gastex.pro which contains all the postscript procedures (this file could
-be in your working folder but it is best placed where the tex.pro file is).
-
-Usage: latex+dvips(+ps2pdf)
+- gastex.sty which contains the definition of all the LaTeX macros. This file
+could be in your working folder or where other .sty files are, e.g.,
+  .../texmf-dist/tex/latex/gastex/gastex.sty
+  or 
+  .../texmf-local/tex/latex/gastex/gastex.sty
+- gastex.pro which contains all the postscript procedures.  This file
+could be in your working folder or where other .pro files are, e.g.,
+  .../texmf-dist/dvips/gastex/gastex.pro
+  or
+  .../texmf-local/dvips/gastex/gastex.pro
+
+Usage: latex+dvips(+ps2pdf) filename.tex
 ------
 - Compile the source file with latex (not pdflatex) and generate the ps file 
 with dvips. One may then use ps2pdf to get a pdf file.
 
+Usage: pdflatex --shell-escape filename.tex
+------
+- Requires the package auto-pst-pdf.  
+
 Remarks:
 --------
-- gastex mainly generates postscript code so the pictures cannot be seen with a
-dvi-viewer. One has to generate a ps file (latex+dvips) and view it with a 
-ps-viewer. One can also generate a pdf file (latex+dvips+ps2pdf) and view 
-it with a pdf-viewer.
-- gastex does not work with pdflatex since it produces postscript code
-which cannot be interpreted by a pdf viewer.  Instead, one should generate
-the pdf file with latex+dvips+ps2pdf.
-
-Examples: 
----------
-- Several examples are provided on the gastex web page at
-http://www.lsv.ens-cachan.fr/~gastin/gastex/gastex.html
-- ex-gastex.tex contains some examples to learn gastex and to test your 
-installation.
-- ex-beamer-gastex.tex shows how gastex may be used with beamer in order to
-produce very nice animated slides.  You have to compile the file through
-latex-dvips-ps2pdf (not pdflatex).
-
-Documentation:
---------------
-See http://www.lsv.ens-cachan.fr/~gastin/gastex/gastex.html
-The best is to learn with the examples (see above).
-Comments in the file gastex.sty provide documentation for all macros.

+ps-viewer or a pdf-viewer.
+
+Documentation and examples:
+---------------------------
+- See http://www.lsv.fr/~gastin/gastex/index.html
+- See also gastex-doc.tex for a quick startup guide on how to use gastex
+with pdflatex and a few examples.
+- Comments in the file gastex.sty also provide documentation for all macros.
 
 Enjoy!

+For the documentation, please see
+\url{http://www.lsv.fr/~gastin/gastex/index.html}.
+
+The package consists of two files \verb|gastex.sty| and \verb|gastex.pro|.
+\begin{itemize}
+  \item \verb|gastex.sty| contains the definition of all \GasTeX macros.
+  This file could be in your working folder but it is best placed where \verb|.sty| files are, e.g.,
+  
+  \verb|.../texmf-dist/tex/latex/gastex/gastex.sty| \\  
+  or \\  
+  \verb|.../texmf-local/tex/latex/gastex/gastex.sty|
+
+  \item  \verb|gastex.pro| which contains all the postscript procedures used to actually draw the pictures.
+  This file could be in your working folder but it is best placed where \verb|.pro| files are, e.g.,
+  
+  \verb|.../texmf-dist/dvips/gastex/gastex.pro| \\
+  or \\  
+  \verb|.../texmf-local/dvips/gastex/gastex.pro|
+\end{itemize}
+
+This documentation file simply contains a few simple examples on how to make figures with
+\GasTeX. It should be compiled with
+\begin{quote}
+  \verb|pdflatex --shell-escape gastex-doc.tex| \\ 
+  or \\
+  \verb|pdflatex --enable-write18 gastex-doc.tex|
+\end{quote}
+
+The first example below is a 2-way deterministic finite state transducer. It consists of 
+a \verb|gpicture| environment which contains the \GasTeX commands for nodes and 
+transitions.
+

+\end{center}
+
+The second one is in Figure~\ref{fig:LR-concat}.  The pictures have been defined at the
+beginning of the \LaTeX\ document, with the \verb|name| and \verb|ignore| optional
+parameters given to the \verb|gpicture| environment.  These pictures are generated but not
+inserted immediately.  Instead, the \verb|\gusepicture| command allows to include each
+named picture, possibly multiple times at different places.
+
+All pictures defined in \verb|gpicture| environments are compiled and stored in a file
+called \verb|filename-pics.pdf|, one picture per page.  These pictures could be included
+in any \LaTeX\ file, possibly another \LaTeX\ file which need not use the \GasTeX package,
+simply by using \verb|\includegraphics| as follows:
+\begin{quote}
+  \verb|\includegraphics[page=2,scale=0.6]{gastex-doc-pics.pdf}|
+
+  \includegraphics[page=2,scale=0.6]{gastex-doc-pics.pdf}
+\end{quote}
+This is convenient for instance when sending the \LaTeX\ file to \verb|Arxiv| or to an 
+editor (journal, proceedings) which does not allow the \verb|--shell-escape| option when 
+compiling with \verb|pdflatex|. Actually, \GasTeX does this automatically for you. When 
+loading the package, set the \verb|recompilepics| option to \verb|false| as follows:
+\begin{quote}
+  \verb|\usepackage[pdflatex,recompilepics=false]{gastex}|
+\end{quote}
+then you may compile without the \verb|--shell-escape| option
+\begin{quote}
+    \verb|pdflatex gastex-doc.tex| 
+\end{quote}
+and \GasTeX automatically calls \verb|\includegraphics| to include the pictures that have 
+been previously generated and stored in the file \verb|gastex-doc-pics.pdf|.
