Managing library outside of GUI (config files, console?)

[Bill Red]

Hi all,
I am looking for a way to manage my libraries outside of the GUI. Are there config files that manage this that I can edit? Is it possible to do it in a console? I have looked and am unable to find anything regarding this. 

I have many folders that I would like to add to libraries, and am hoping there is a way I can do this, and edit it without manually clicking through the folders on the GUI for the library to add them all, one by one.

Any help would be greatly appreciated.
Thanks in advance.

Outside of the UI, you'd have to use the API. There are no config files for adding new libraries.

Darn. That is unfortunate.
Thank you for the response!
