+1) ABOUT
+========
+
+This is the Python package 'antlr3', which is required to use parsers created
+by the ANTLR3 tool. See <http://www.antlr.org/> for more information about
+ANTLR3.
+
+
+2) STATUS
+=========
+
+The Python target for ANTLR3 is still in beta. Documentation is lacking, some
+bits of the code is not yet done, some functionality has not been tested yet.
+Also the API might change a bit - it currently mimics the Java implementation,
+but it may be made a bit more pythonic here and there.
+
+WARNING: Currently the runtime library for V3.1 is not compatible with
+recognizers generated by ANTLR V3.0.x. If you are an application developer,
+then the suggested way to solve this is to package the correct runtime with
+your application. Installing the runtime in the global site-packages directory
+may not be a good idea.
+It is still undetermined, if a future release of the V3.1 runtime will be
+compatible with V3.0.x recognizers or if future runtimes V3.2+ will be
+compatible with V3.1 recognizers.
+Sorry for the inconvenience.
+
+
+3) DOWNLOAD
+===========
+
+This runtime is part of the ANTLR distribution. The latest version can be found
+at <http://www.antlr.org/download.html>.
+
+If you are interested in the latest, most bleeding edge version, have a look at
+the perforce depot at <http://fisheye2.cenqua.com/browse/antlr>. There are
+tarballs ready to download, so you don't have to install the perforce client.
+
+
+4) INSTALLATION
+===============
+
+Just like any other Python package:
+$ python setup.py install
+
+See <http://docs.python.org/inst/> for more information.
+
+
+5) DOCUMENTATION
+================
+
+Documentation (as far as it exists) can be found in the wiki
+<http://www.antlr.org/wiki/display/ANTLR3/Antlr3PythonTarget>
+
+
+6) REPORTING BUGS
+=================
+
+Please send bug reports to the ANTLR mailing list 
+<http://www.antlr.org:8080/mailman/listinfo/antlr-interest> or
+<pink@odahoda.de>.
+
+Existing bugs may appear someday in the bugtracker:
+<http://www.antlr.org:8888/browse/ANTLR>
+
+
+7) HACKING
+==========
+
+Only the runtime package can be found here. There are also some StringTemplate
+files in 'src/org/antlr/codegen/templates/Python/' and some Java code in
+'src/org/antlr/codegen/PythonTarget.java' (of the main ANTLR3 source
+distribution).
+
+If there are no directories 'tests' and 'unittests' in 'runtime/Python', you
+should fetch the latest ANTLR3 version from the perforce depot. See section
+DOWNLOAD.
+You'll need java and ant in order to compile and use the tool.
+Be sure to properly setup your CLASSPATH.
+(FIXME: is there some generic information, how to build it yourself? I should
+point to it to avoid duplication.)
+
+You can then use the commands
+$ python setup.py unittest
+$ python setup.py functest
+to ensure that changes do not break existing behaviour.
+
+Please send patches to <pink@odahoda.de>. For larger code contributions you'll
+have to sign the "Developer's Certificate of Origin", which can be found on
+<http://www.antlr.org/license.html> or use the feedback form at
+<http://www.antlr.org/misc/feedback>.
