    Bootstrapping an isolated environment
    =====================================
    Sometimes it is useful to install ``zc.buildout`` and its dependencies
    directly in ``eggs`` directory and to generate a ``buildout`` script in
    the ``bin`` directory that uses the version in ``eggs`` directory,
    instead of relying on the package available in the environment.
    One way to achieve this uses the ``extra-paths`` option of ``buildout``
    section: by setting it to empty value, packages outside of ``eggs``
    or ``develop-eggs`` directories will not be considered when looking
    for already installed eggs. Then the ``bootstrap`` command will
    install ``zc.buildout`` and its dependencies from scratch in ``eggs``.
    .. code-block:: console
    buildout buildout:extra-paths= bootstrap
    After this, the generated ``bin/buildout`` script will use the packages
    installed in ``eggs`` directory instead of those in the environment and
    preserve the isolation from the environment, even without setting
    ``extra-paths``. That is because the default value for ``extra-paths``
    only considers the paths where ``zc.buildout`` and its dependencies are
    found, and in this case that is only the ``eggs`` directory.

    Setting this to 'legacy' enables the legacy behavior of
    scanning the paths of the distributions of zc.buildout itself

    Patching eggs before installation
    ---------------------------------
    The SlapOS extensions of ``zc.recipe.egg`` supports applying patches before installing eggs.
    The syntax is to use a version with the magic string ``SlapOSPatched`` plus the number of
    patches to apply.
    Let's use a patch for demoneeded egg:
    >>> write(sample_buildout, 'demoneeded.patch',
    ... r"""diff -ru before/demoneeded-1.1/eggrecipedemoneeded.py after/demoneeded-1.1/eggrecipedemoneeded.py
    ... --- before/demoneeded-1.1/eggrecipedemoneeded.py 2020-09-08 09:27:36.000000000 +0200
    ... +++ after/demoneeded-1.1/eggrecipedemoneeded.py 2020-09-08 09:46:16.482243822 +0200
    ... @@ -1,3 +1,3 @@
    ... -y=1
    ... +y="patched demoneeded"
    ... def f():
    ... pass
    ... \ No newline at end of file
    ... """)
    First, we install demoneeded directly:
    >>> write(sample_buildout, 'buildout.cfg',
    ... """
    ... [buildout]
    ... parts = demoneeded
    ...
    ... [demoneeded]
    ... recipe = zc.recipe.egg:eggs
    ... eggs = demoneeded
    ... find-links = %(server)s
    ... index = %(server)s/index
    ... demoneeded-patches =
    ... ./demoneeded.patch#4b8ad56711dd0d898a2b7957e9604079
    ... demoneeded-patch-options = -p2
    ...
    ... [versions]
    ... demoneeded = 1.1+SlapOSPatched001
    ... """ % dict(server=link_server))
    When running buildout, we have a warning that a different version is installed, but that's not fatal.
    >>> print_(system(buildout), end='')
    Installing demoneeded.
    patching file eggrecipedemoneeded.py
    Installing demoneeded 1.1
    Caused installation of a distribution:
    demoneeded 1.1+slapospatched001
    with a different version.
    The installed egg has the slapospatched001 marker
    >>> ls(sample_buildout, 'eggs')
    d demoneeded-1.1+slapospatched001-pyN.N.egg
    - setuptools-0.7-py2.3.egg
    d zc.buildout-1.0-py2.3.egg
    The code of the egg has been patched:
    >>> import glob
    >>> import os.path
    >>> cat(glob.glob(os.path.join(sample_buildout, 'eggs', 'demoneeded-1.1+slapospatched001*', 'eggrecipedemoneeded.py'))[0])
    y="patched demoneeded"
    def f():
    pass
    Reset the state and also remove the installed egg
    >>> remove('.installed.cfg')
    >>> rmdir(glob.glob(os.path.join(sample_buildout, 'eggs', 'demoneeded-1.1+slapospatched001*'))[0])
    In the previous example we applied patches to an egg installed directly, but
    the same technique can be used to apply patches on eggs installed as dependencies.
    In this example we install demo and apply a patch to demoneeded, which is a dependency to demo.
    >>> write(sample_buildout, 'buildout.cfg',
    ... """
    ... [buildout]
    ... parts = demo
    ...
    ... [demo]
    ... recipe = zc.recipe.egg
    ... eggs = demo
    ... find-links = %(server)s
    ... index = %(server)s/index
    ... demoneeded-patches =
    ... ./demoneeded.patch#4b8ad56711dd0d898a2b7957e9604079
    ... demoneeded-patch-options = -p2
    ...
    ... [versions]
    ... demoneeded = 1.1+SlapOSPatched001
    ... """ % dict(server=link_server))
    When running buildout, we also have that warning that a different version is installed.
    >>> print_(system(buildout), end='')
    Installing demo.
    Getting distribution for 'demo'.
    Got demo 0.3.
    patching file eggrecipedemoneeded.py
    Installing demoneeded 1.1
    Caused installation of a distribution:
    demoneeded 1.1+slapospatched001
    with a different version.
    Generated script '/sample-buildout/bin/demo'.
    The installed egg has the slapospatched001 marker
    >>> ls(sample_buildout, 'eggs')
    d demo-0.3-pyN.N.egg
    d demoneeded-1.1+slapospatched001-pyN.N.egg
    - setuptools-0.7-py2.3.egg
    d zc.buildout-1.0-py2.3.egg
    If we run the demo script we see the patch was applied:
    >>> print_(system(join(sample_buildout, 'bin', 'demo')), end='')
    3 patched demoneeded
