Just an FYI. As part of the 1.3.0 release, the contrib libraries are getting a facelift:
http://dev.clojure.org/display/design/Contrib+Library+Names clojure.contrib.command-line will become clojure.tools.cli - I'm not sure who the new maintainer is but they would be the person best placed to address your suggestion since the old contrib libraries will not be updated. I haven't used the command-line library so I can't really comment but, on the surface, the ability to print help from multiple places sounds useful.
