 This is Python version 3.5.0 beta 4
 ===================================

 Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011,

 Python 3.x is a new version of the language, which is incompatible with the 2.x
 line of releases.  The language is mostly the same, but many details, especially
 how built-in objects like dictionaries and strings work, have changed
 considerably, and a lot of deprecated features have finally been removed.


 Build Instructions
 ------------------

 On Unix, Linux, BSD, OSX, and Cygwin:

     ./configure
     make
     make test
     sudo make install

 This will install Python as python3.

 You can pass many options to the configure script; run "./configure --help" to
 find out more.  On OSX and Cygwin, the executable is called python.exe;
 elsewhere it's just python.

 On Mac OS X, if you have configured Python with --enable-framework, you should
 use "make frameworkinstall" to do the installation.  Note that this installs the
 Python executable in a place that is not normally on your PATH, you may want to
 set up a symlink in /usr/local/bin.

 On Windows, see PCbuild/readme.txt.

 If you wish, you can create a subdirectory and invoke configure from there.  For
 example:

     mkdir debug
     cd debug
     ../configure --with-pydebug
     make
     make test

 (This will fail if you *also* built at the top-level directory.  You should do a
 "make clean" at the toplevel first.)


 What's New
 ----------

 We try to have a comprehensive overview of the changes in the "What's New in
 Python 3.5" document, found at

     http://docs.python.org/3.5/whatsnew/3.5.html

 For a more detailed change log, read Misc/NEWS (though this file, too, is
 incomplete, and also doesn't list anything merged in from the 2.7 release under
 development).

 If you want to install multiple versions of Python see the section below
 entitled "Installing multiple versions".


 Documentation
 -------------

 Documentation for Python 3.5 is online, updated daily:

     http://docs.python.org/3.5/

 It can also be downloaded in many formats for faster access.  The documentation
 is downloadable in HTML, PDF, and reStructuredText formats; the latter version
 is primarily for documentation authors, translators, and people with special
 formatting requirements.

 If you would like to contribute to the development of Python, relevant
 documentation is available at:

     http://docs.python.org/devguide/

 For information about building Python's documentation, refer to Doc/README.txt.


 Converting From Python 2.x to 3.x
 ---------------------------------

 Python starting with 2.6 contains features to help locating code that needs to
 be changed, such as optional warnings when deprecated features are used, and
 backported versions of certain key Python 3.x features.

 A source-to-source translation tool, "2to3", can take care of the mundane task
 of converting large amounts of source code.  It is not a complete solution but
 is complemented by the deprecation warnings in 2.6.  See
 http://docs.python.org/3.5/library/2to3.html for more information.


 Testing
 -------

 To test the interpreter, type "make test" in the top-level directory.  The test
 set produces some output.  You can generally ignore the messages about skipped
 tests due to optional features which can't be imported.  If a message is printed
 about a failed test or a traceback or core dump is produced, something is wrong.

 By default, tests are prevented from overusing resources like disk space and
 memory.  To enable these tests, run "make testall".

 IMPORTANT: If the tests fail and you decide to mail a bug report, *don't*
 include the output of "make test".  It is useless.  Run the failing test
 manually, as follows:

         ./python -m test -v test_whatever

 (substituting the top of the source tree for '.' if you built in a different
 directory).  This runs the test in verbose mode.


 Installing multiple versions
 ----------------------------

 On Unix and Mac systems if you intend to install multiple versions of Python
 using the same installation prefix (--prefix argument to the configure script)
 you must take care that your primary python executable is not overwritten by the
 installation of a different version.  All files and directories installed using
 "make altinstall" contain the major and minor version and can thus live
 side-by-side.  "make install" also creates ${prefix}/bin/python3 which refers to
 ${prefix}/bin/pythonX.Y.  If you intend to install multiple versions using the
 same prefix you must decide which version (if any) is your "primary" version.
 Install that version using "make install".  Install all other versions using
 "make altinstall".

 For example, if you want to install Python 2.6, 2.7 and 3.5 with 2.7 being the
 primary version, you would execute "make install" in your 2.7 build directory
 and "make altinstall" in the others.


 Issue Tracker and Mailing List
 ------------------------------

 We're soliciting bug reports about all aspects of the language.  Fixes are also
 welcome, preferable in unified diff format.  Please use the issue tracker:

     http://bugs.python.org/

 If you're not sure whether you're dealing with a bug or a feature, use the
 mailing list:

     python-dev@python.org

 To subscribe to the list, use the mailman form:

     http://mail.python.org/mailman/listinfo/python-dev/


 Proposals for enhancement
 -------------------------

 If you have a proposal to change Python, you may want to send an email to the
 comp.lang.python or python-ideas mailing lists for inital feedback.  A Python
 Enhancement Proposal (PEP) may be submitted if your idea gains ground.  All
 current PEPs, as well as guidelines for submitting a new PEP, are listed at
 http://www.python.org/dev/peps/.
