Cliquet has been folded into the Kinto package under the new name
kinto.core. You should update your code to import kinto.core
instead of cliquet, and all cliquet.* settings are now
prefixed with kinto instead. See
https://mail.mozilla.org/pipermail/kinto/2016-May/000119.html for more
about the background for this decision.
Cliquet is a toolkit to ease the implementation of HTTP microservices, such as data-driven REST APIs.
