It abstracts away almost all the boilerplate App Engine for Java requires, and makes Lispy, interactive, REPL-based development trivial to set up for App Engine. I have not yet finished making Clojure wrappers for all of App Engine's services, but datastore, memcache, and user authentication are already available.
I'll be giving a talk about it at the NYC Clojure Users Group meeting this coming Wednesday (October 20th).
Thereby defying the purpose of refactoring code.
