Currently, it is just a static site hosting a v0.4 Common Lisp Project Index as static files. See the CLPI repository for a detailed specification of the index. This index was created using the ql-clpi project.
To use this as a source for CLPM, add the following to your sources.conf file or your clpmfile, changing the name as appropriate:
("quicklisp" :type :ql-clpi :url "https://quicklisp.common-lisp-project-index.org/")This site is maintained by the CLPM developers.
