        Motivation
        ----------
        
        This project is a playground to test some optimization strategies in Python,
        but is essentially an exemple of a real-life Python package, and serve me as
        a boilerplate project for future CLI.
        
        
        Development philosophy
        ----------------------
        
        1. First create something that work (to provide business value).
        2. Then something that's beautiful (to lower maintenance costs).
        3. Finally works on performance (to avoid wasting time on premature
           optimizations).
        
        
        Install
        -------
        
        This package is available on PyPi, so you can install the latest stable release
        and its dependencies with a simple `pip` call:
        
        .. code-block:: bash
        
            $ pip install chessboard
        
        
        Usage
        -----
        
        .. code-block:: bash
        
            $ chessboard --help
            Usage: chessboard [OPTIONS]
        
              Python CLI to explore chessboard positions.
        
            Options:
              --version             Show the version and exit.

        Development
        -----------
        
        Check out latest development branch:
        
        .. code-block:: bash
        
            $ git clone git@github.com:kdeldycke/chessboard.git

        Stability policy
        ----------------
        
        Here is a bunch of rules we're trying to follow regarding stability:
        
        * Patch releases (``0.x.n`` → ``0.x.(n+1)`` upgrades) are bug-fix only. These
          releases must not break anything and keeps backward-compatibility with
          ``0.x.*`` and ``0.(x-1).*`` series.
        
        * Minor releases (``0.n.*`` → ``0.(n+1).0`` upgrades) includes any non-bugfix
          changes. These releases must be backward-compatible with any ``0.n.*``
          version but are allowed to drop compatibility with the ``0.(n-1).*`` series
          and below.
        
        * Major releases (``n.*.*`` → ``(n+1).0.0`` upgrades) are not planned yet:
          we're still in beta and the final feature set of the ``1.0.0`` release is not
          decided yet.
        
        
        Release process
        ---------------
        
        Start from the ``develop`` branch:
        
        .. code-block:: bash
        
            $ git clone git@github.com:kdeldycke/chessboard.git
            $ git checkout develop
        
        Revision should already be set to the next version, so we just need to set the
        released date in the changelog:
        
        .. code-block:: bash
        
            $ vi ./CHANGES.rst
        
        Create a release commit, tag it and merge it back to ``master`` branch:
        
        .. code-block:: bash
        
            $ git add ./chessboard/__init__.py ./CHANGES.rst
            $ git commit -m "Release vX.Y.Z"
            $ git tag "vX.Y.Z"
            $ git push
            $ git push --tags
            $ git checkout master
            $ git pull
            $ git merge "vX.Y.Z"
            $ git push
        
        Push packaging to the `test cheeseshop
        <https://wiki.python.org/moin/TestPyPI>`_:
        
        .. code-block:: bash
        
            $ pip install wheel
            $ python ./setup.py register -r testpypi
            $ rm -rf ./build ./dist
            $ python ./setup.py sdist bdist_egg bdist_wheel upload -r testpypi
        
        Publish packaging to `PyPi <https://pypi.python.org>`_:
        
        .. code-block:: bash
        
            $ python ./setup.py register -r pypi
            $ rm -rf ./build ./dist
            $ python ./setup.py sdist bdist_egg bdist_wheel upload -r pypi
        
        Bump revision back to its development state:
        
        .. code-block:: bash
        
            $ pip install bumpversion
            $ git checkout develop
            $ bumpversion --verbose patch
            $ git add ./chessboard/__init__.py ./CHANGES.rst
            $ git commit -m "Post release version bump."
            $ git push
        
        Now if the next revision is no longer bug-fix only:
        
        .. code-block:: bash
        
            $ bumpversion --verbose minor
            $ git add ./chessboard/__init__.py ./CHANGES.rst
            $ git commit -m "Next release no longer bug-fix only. Bump revision."
            $ git push
