One of the concerns I've had with clojurescript is the filesize of the generated js. Are there any techniques for reducing the filesize of the generated js? (I'm aware that closure compiler advanced mode is used). Clojurescript projects I've looked at seem to compile to a minimum filesize of ~70k (uncompressed). Using closure compiler advanced mode I'd like a bare bones hello world project to compile to something closer to alert("Hello World").

I understand yours includes jayq so not referring specifically to yours, however ideally I'd still like to see it compiled out to something along the lines of:

$(document).ready(function(){$("#btn").click(function() { alert("Hi!");});});

Exception in thread "main" java.lang.ClassNotFoundException: clojurescript-ohpointone.core

I installed the stable release of leiningen and it works fine.
