org.eclipse.osgi.framework.console.CommandProvider
When an object wants to provide a number of commands to the console, it should register an object with this interface. Some console can then pick this up and execute command lines. The SERVICE_RANKING registration property can be used to influence the order that a CommandProvider gets called. Specify a value less than Integer.MAXVALUE, where higher is more significant. The default value if SERVICE_RANKING is not set is 0.
The interface contains only methods for the help. The console should use inspection to find the commands. All public commands, starting with a '_' and taking a CommandInterpreter as parameter will be found. E.g.
```
 public Object _hello( CommandInterpreter intp ) { return "hello " + intp.nextArgument(); } 
```
Clients may implement this interface.
