+python-atomicwrites
+===================
+
+.. image:: https://travis-ci.org/untitaker/python-atomicwrites.svg?branch=master
+    :target: https://travis-ci.org/untitaker/python-atomicwrites
+
+.. image:: https://ci.appveyor.com/api/projects/status/vadc4le3c27to59x/branch/master?svg=true

+
+Atomic file writes.
+
+.. code-block:: python
+
+    from atomicwrites import atomic_write
+
+    with atomic_write('foo.txt', overwrite=True) as f:
+        f.write('Hello world.')
+        # "foo.txt" doesn't exist yet.
+
+    # Now it does.
+
+
+Features that distinguish it from other similar libraries (see `Alternatives and Credit`_):
+
+- Race-free assertion that the target file doesn't yet exist. This can be
+  controlled with the ``overwrite`` parameter.
+
+- Windows support, although not well-tested. The MSDN resources are not very
+  explicit about which operations are atomic.
+
+- Simple high-level API that wraps a very flexible class-based API.
+
+- Consistent error handling across platforms.
+
+
+How it works
+============
+
+It uses a temporary file in the same directory as the given path. This ensures
+that the temporary file resides on the same filesystem.
+
+The temporary file will then be atomically moved to the target location: On
+POSIX, it will use ``rename`` if files should be overwritten, otherwise a
+combination of ``link`` and ``unlink``. On Windows, it uses MoveFileEx_ through
+stdlib's ``ctypes`` with the appropriate flags.
+
+Note that with ``link`` and ``unlink``, there's a timewindow where the file
+might be available under two entries in the filesystem: The name of the
+temporary file, and the name of the target file.
+
+Also note that the permissions of the target file may change this way. In some
+situations a ``chmod`` can be issued without any concurrency problems, but
+since that is not always the case, this library doesn't do it by itself.
+
+.. _MoveFileEx: https://msdn.microsoft.com/en-us/library/windows/desktop/aa365240%28v=vs.85%29.aspx
+
+fsync
+-----
+
+On POSIX, ``fsync`` is invoked on the temporary file after it is written (to
+flush file content and metadata), and on the parent directory after the file is
+moved (to flush filename).
+
+``fsync`` does not take care of disks' internal buffers, but there don't seem
+to be any standard POSIX APIs for that. On OS X, ``fcntl`` is used with
+``F_FULLFSYNC`` instead of ``fsync`` for that reason.
+
+On Windows, `_commit <https://msdn.microsoft.com/en-us/library/17618685.aspx>`_
+is used, but there are no guarantees about disk internal buffers.
+
+Alternatives and Credit
+=======================
+
+Atomicwrites is directly inspired by the following libraries (and shares a
+minimal amount of code):
+
+- The Trac project's `utility functions
+  <http://www.edgewall.org/docs/tags-trac-0.11.7/epydoc/trac.util-pysrc.html>`_,
+  also used in `Werkzeug <http://werkzeug.pocoo.org/>`_ and
+  `mitsuhiko/python-atomicfile
+  <https://github.com/mitsuhiko/python-atomicfile>`_. The idea to use
+  ``ctypes`` instead of ``PyWin32`` originated there.
+
+- `abarnert/fatomic <https://github.com/abarnert/fatomic>`_. Windows support
+  (based on ``PyWin32``) was originally taken from there.
+
+Other alternatives to atomicwrites include:
+
+- `sashka/atomicfile <https://github.com/sashka/atomicfile>`_. Originally I
+  considered using that, but at the time it was lacking a lot of features I
+  needed (Windows support, overwrite-parameter, overriding behavior through
+  subclassing).
+
+- The `Boltons library collection <https://github.com/mahmoud/boltons>`_
+  features a class for atomic file writes, which seems to have a very similar
+  ``overwrite`` parameter. It is lacking Windows support though.

+- On UNIX systems, errors from the Python stdlib calls are thrown.
+- On Windows systems, errors from Python's ``ctypes`` are thrown.

+In either case, the ``errno`` attribute on the thrown exception maps to an
