Pack all clojure-contrib sources into a JAR. Compile those that can be compiled standalone if the clojure.jar property points us to clojure.jar. WARNING: You have not defined a path to clojure.jar so I can't compile files. This will cause some parts of clojure.contrib not to work (e.g., pretty print). To enable compiling, run "ant -Dclojure.jar=<...path to clojure.jar..>" Locating namespaces to compile ... Compiling Clojure namespaces ...
