docs: An execution context created using :mod:`executor.contexts`.
  
          The value of :attr:`context` defaults to a
          :class:`~executor.contexts.LocalContext` object with the following
          characteristics:
  
          - The working directory of the execution context is set to the
            value of :attr:`directory`.
  
          - The environment variable given by :data:`DIRECTORY_VARIABLE` is set
            to the value of :attr:`directory`.
  
          :raises: :exc:`.MissingPasswordStoreError` when :attr:`directory`
                   doesn't exist.
