"""
Module for managing the LXD daemon and its containers.

.. versionadded:: 2019.2.0

`LXD(1)`_ is a container "hypervisor". This execution module provides
several functions to help manage it and its containers.

.. note::

    - `pylxd(2)`_ version >=2.2.5 is required to let this work,
      currently only available via pip.

        To install on Ubuntu:

        $ apt-get install libssl-dev python-pip
        $ pip install -U pylxd

    - you need lxd installed on the minion
      for the init() and version() methods.

    - for the config_get() and config_get() methods
      you need to have lxd-client installed.
