 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 3.1" document, found at

     http://docs.python.org/dev/3.1/whatsnew/3.1.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 3.1 is online, updated twice a day:

     http://docs.python.org/dev/3.1/

 All documentation is also available online at the Python web site
 (http://docs.python.org/, see below).  It is available online for
 occasional reference, or can be downloaded in many formats for faster
 access.  The documentation is downloadable in HTML, PostScript, PDF,
 LaTeX (through 2.5), and reStructuredText (2.6+) formats; the LaTeX and
 reStructuredText versions are primarily for documentation authors,
 translators, and people with special formatting requirements.


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

 Python starting with 2.6 will contain 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/dev/py3k/library/2to3.html for more information.


 Testing
 -------

 To test the interpreter, type "make test" in the top-level directory.
 This runs the test set twice (once with no compiled files, once with
 the compiled files left by the previous test run).  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.  On some Linux systems (those
 that are not yet using glibc 6), test_strftime fails due to a
 non-standard implementation of strftime() in the C library. Please
 ignore this, or upgrade to glibc version 6.

 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 Lib/test/regrtest.py -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 2.5, 2.6 and 3.0 with 2.6 being
 the primary version, you would execute "make install" in your 2.6 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/.
