Since the version 1.7.2 a new #includedir directive is available in sudoers. To keep backward compatibility with old sudo versions the common::concatfilepart definition is used. Some default distribution versions are defined in sudo::params::majversion but it is also possible to specify your own version in the global parameter $sudo_version
The definition sudo::directive provides a simple way to write sudo configurations parts. If you use a sudo version >= 1.7.2, the sudo directive part is validated via visudo and removed if syntax is not correct.
