This family will be desactived if "proxy_mode" is not "manual proxy configuration".
Desactived a variable or a family means that this variable will never be accessible.
The "manual" mode structural descriptions are write in a new files to separate things. But Rougail will concatenate variables and families.
We create a family, which will contain other variables.
This family has:
- a description
- a type
As there is no variable inside this family, the type is mandatory. Without it, Rougail will create a variable.
In fact, this family will be deleted by Rougail too because it is empty.
