How can I generate a complete list of libraries and presets, etc. for Halion, GA on my system?

Ok, I am going to assume that there is no list of libraries and presets, layers, programs, and multis for Halion. So, how can I generate one? I want to get a list of those that are on my system so that I can more easily find things in combination with other types of libraries.

The same would apply for Groove Agent.

Is there a tool that can read vstsound files and extract that information?
