For easier maintenance, implementing multiple filter groups often also involves linking the config and list files in a particular way. The setup process, which can be rather daunting, can be done automatically by one of these DansGuardian management tools. It is usually done just once.
Sometimes an administrator wants to know if the process has already been done, and if so which options were selected. This addresses that issue by displaying the options that were used to set up the links between config&list files for multiple filter groups.
The possible general schemes are:
this means each list file will affect not only its own filter group but also all other filter groups below (or above) it. So for example if your filter groups are "temps", "employees", "managers", and "executives", any change to the exception... lists for "managers" will also automatically affect "executives", and any changes to the banned... lists for "managers" will also automatically affect "employees" and "temps".
this means each filter group will be given own completely independent lists, which will neither affect nor be affected by any other filter group
this means each filter group has its own lists, yet it also references a list which is common to all filter groups. In other words there are common "base" lists on which individual filter groups then elaborate.
