+
+GasTeX: Graphs and Automata Simplified in TeX
+
+GasTeX is a set of LaTeX macros which allow to draw very easily graphs,
+automata, nets, diagrams, etc... under the picture environment of LaTeX.
+
+Author:
+-------
+Paul Gastin <http://www.lsv.ens-cachan.fr/~gastin>
+
+Copyright: 2006 by Paul Gastin
+----------
+This program can be redistributed and/or modified under the terms
+of the LaTeX Project Public License Distributed from CTAN
+archives in directory macros/latex/base/lppl.txt.
+
+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)
+------
+- 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.
+
+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.
+
+Enjoy! \ No newline at end of file
