(cache-jars! conf jar-paths)(cache-jars! conf m2-path jar-paths)
Copy JARs from local Maven-repository `jar-paths` to HDFS cache at `m2-path`,
updating `conf` to add the cached JARs to the job classpath.


(launch! conf f & args)
Ensure job JAR and dependencies are up-to-date.  Derive a Hadoop
configuration from `conf` and configure it to use the project job JAR and
dependencies.  Apply function `f` to the resulting configuration followed by
`args` and return the result.
