Description:

def install(name=None, refresh=False, version=None, pkgs=None, **kwargs):
    '''
    Install packages using the pkgutil tool.

    CLI Example:

    .. code-block:: bash

        salt '*' pkg.install <package_name>
        salt '*' pkg.install SMClgcc346


    Multiple Package Installation Options:

    pkgs
        A list of packages to install from OpenCSW. Must be passed as a python
        list.

        CLI Example:

        .. code-block:: bash

            salt '*' pkg.install pkgs='["foo", "bar"]'
            salt '*' pkg.install pkgs='["foo", {"bar": "1.2.3"}]'


    Returns a dict containing the new package names and versions::

        {'<package>': {'old': '<old-version>',
                       'new': '<new-version>'}}
