public class ToolRunner extends ToolExecutor implements java.util.concurrent.Callable<java.lang.Integer>, org.springframework.beans.factory.InitializingBean
ToolRunner allowing for an easier configuration and execution
 of Tool  instances inside Spring.
 Optionally returns the execution result (as an int per Tool.run(String[])).
 
 To make the runner execute at startup, use setRunAtStartup(boolean).
