What is an Eclipse Spring STS "Config Set" good for?

I have the Spring STS plugin activated within my Eclipse project. Doing this enabled many cool Spring features including specialized management of Spring bean files. However, I noticed that the project settings for Spring allows for the creation of "开发者_开发百科Config Sets" -- which look like groups of bean configuration files.

I cannot find documentation for this feature anywhere...anyone know what it does?

I use "config sets" to display the dependencies between Spring beans in several different context files.
