This is compiler for the Clojure programming language that targets C as a backend.
Before you can run anything make sure you have GLib 2 and the Boehm-Demers-Weiser garbage collector installed. If
pkg-config --cflags glib-2.0
pkg-config --cflags bdw-gc
don't report errors you should be good.
Make sure you're using Leiningen 2 - older versions of Leiningen won't work. Run the testsuite:
lein test
All tests should pass.
