Ubiquitous is a very easy-to-use library for persistent configuration storage. It automatically takes care of finding a suitable place to save your data, and provides simple functions to access and modify the data within.

The project can be found on github including a fully documented symbol index and a getting started tutorial.
As of 2015, ubiquitous is on Quicklisp.
