I have a few libraries that are not yet in Quicklisp, either because they're in development or I doubt they'll be useful to others. I've been adding them to my projects as git submodules, but I find submodules a pain to maintain. I invented cl-autorepo to make it easier, e.g.:
(cl-autorepo:add-system "fsdb" "https://github.com/billstclair/fsdb" :git)
(ql:quickload "fsdb")
