notes:
|
|
- If a rule declares a group_name and that group doesn't exist, it will be

automatically created. In that case, group_desc should be provided as well.
|
|
The module will refuse to create a depended-on group without a description.
|
|
- Preview diff mode support is added in version 2.7.
