My changes are here: http://github.com/fitzgen/parenscript They are a pretty big gross hack. Most of the changes are just adding the files necessary to make it a Narwhal[1] package but I also had to write a little command line script for parenscript. I'm sure it is horrible, I'm very inexperienced with lisp. I just thought you guys might want to know about the changes. The coolest thing is that Narwhal will give you a REPL for parenscript. Go ahead and incorporate the changes if you want, or not, just letting you know what I have done. Thanks for a wonderful project! _Nick_ [1] http://narwhaljs.org/
