> The javadocs in {{org.apache.hadoop.util.Tool}} contain an example to use the tool runner
to invoke a tool.
> If you copy and paste the example into a java file it doesn't even compile
> # {{job.setInputPath()}} isn't there
> # {{job.setOutputPath()}} isn't there
> # {{job.waitForCompletion()}} isn't invoked
> # the {{Tool.run()}} implementation doesn't contain a return statement.
> The processed javadocs are online: [http://hadoop.apache.org/common/docs/r1.0.3/api/org/apache/hadoop/util/Tool.html]
