title: how are you expected to install the clojure modular contribs?
body: <p>The old monolithic clojure.contrib was available as a .jar from the same place you got the clojure .jar, and you used it by pointing your classpath at it.  As far as I can tell, the new modular contribs aren't available in the clojure .jar -- instead, they exist as source files on github.  What's the expected way for you to use them?  Say, e.g., I wanted to use something in clojure.math.numeric-tower.  What would I do?</p>
  
  <p>I've found <a href="https://stackoverflow.com/questions/8617541/how-do-i-install-clojure-1-3-with-contribs-on-rhel-6-1-jdk7">How do I install Clojure 1.3 with contribs on RHEL 6.1 / JDK7?</a>, but the only answer ("use leiningen") isn't detailed enough for me to figure out.  (Searching clojars for numeric-tower yields... nothing.)</p>
