  desc "Windows package management.

    This provider supports either MSI or self-extracting executable installers.

    This provider requires a `source` attribute when installing the package.
    It accepts paths to local files, mapped drives, or UNC paths.

    This provider supports the `install_options` and `uninstall_options`
    attributes, which allow command-line flags to be passed to the installer.
    These options should be specified as an array where each element is either
    a string or a hash.

    If the executable requires special arguments to perform a silent install or
    uninstall, then the appropriate arguments should be specified using the
    `install_options` or `uninstall_options` attributes, respectively.  Puppet
    will automatically quote any option that contains spaces."
