    Provides information about a OS distribution.

    This package creates a private module-global instance of this class with

    By using default initialization arguments, that module-global instance
    returns data about the current OS distribution (i.e. the distro this
    package runs on).

    Normally, it is not necessary to create additional instances of this class.
    However, in situations where control is needed over the exact data sources

    distro release file, or a specific os-release file, or without invoking the

        The initialization method of this class gathers information from the

        Subsequent access to the information items uses these private instance

        Parameters:

        * ``include_lsb`` (bool): Controls whether the
          `lsb_release command output`_ is included as a data source.

          If the lsb_release command is not available in the program execution
          path, the data source for the lsb_release command will be empty.

        * ``os_release_file`` (string): The path name of the
          `os-release file`_ that is to be used as a data source.

          An empty string (the default) will cause the default path name to
          be used (see `os-release file`_ for details).

          If the specified or defaulted os-release file does not exist, the
          data source for the os-release file will be empty.

        * ``distro_release_file`` (string): The path name of the
          `distro release file`_ that is to be used as a data source.

          An empty string (the default) will cause a default search algorithm
          to be used (see `distro release file`_ for details).

          If the specified distro release file does not exist, or if no default
          distro release file can be found, the data source for the distro
          release file will be empty.

        * ``include_uname`` (bool): Controls whether uname command output is
          included as a data source. If the uname command is not available in
          the program execution path the data source for the uname command will
          be empty.

        Public instance attributes:

        * ``os_release_file`` (string): The path name of the
          `os-release file`_ that is actually used as a data source. The
          empty string if no distro release file is used as a data source.

        * ``distro_release_file`` (string): The path name of the
          `distro release file`_ that is actually used as a data source. The
          empty string if no distro release file is used as a data source.

        * ``include_lsb`` (bool): The result of the ``include_lsb`` parameter.
          This controls whether the lsb information will be loaded.

        * ``include_uname`` (bool): The result of the ``include_uname``
          parameter. This controls whether the uname information will
          be loaded.

        Raises:

        * :py:exc:`IOError`: Some I/O issue with an os-release file or distro
          release file.

        * :py:exc:`subprocess.CalledProcessError`: The lsb_release command had
          some issue (other than not being available in the program execution
          path).
