 #   [*priority*]
 #     Prefix file name with $priority
 #     Default: 10
 #
 #   [*content*]
 #     Content of configuration snippet.
 #     Default: undef
 #
 #   [*source*]
 #     Source of configuration snippet.
 #     Default: undef
 #
 #   [*sudo_config_dir*]
 #     Where to place configuration snippets.
 #     Only set this, if your platform is not supported or
 #     you know, what you're doing.
 #     Default: auto-set, platform specific
 #
 # Actions:
 #   Installs sudo configuration snippets
 #
 # Requires:
