1) they need to be public, and 2) you may have to use the new DLLs -- I can't
remember if 2.1.1 handled this.

Here's a demo.  Being a test program, it deliberately does things the
hard way, i.e. it wasn't written for pedagogical purposes.  You
definitely need new DLLs for this.  The key is the addition of the addOption
method.

import swarm.Globals;
import swarm.SwarmEnvironmentC;
import swarm.SwarmEnvironmentCImpl;
import swarm.SwarmEnvironmentImpl;
import swarm.defobj.Arguments;
import swarm.defobj.ArgumentsC;
import swarm.defobj.ArgumentsCImpl;
import swarm.defobj.ArgumentsImpl;
import swarm.defobj.Zone;


public class TestArguments {
  static void main (String args[]) {
    Zone aZone = Globals.env.globalZone;
    
    ArgumentsC argumentsC = new ArgumentsCImpl (new ArgumentsImpl ());
    Arguments arguments;

    int i, len = args.length;
    String argv[] = new String[1 + len];

    argv[0] = "TestArguments";

    for (i = 0; i < len; i++)
      argv[1 + i] = args[i];

    argumentsC.createBegin (aZone);
    argumentsC.setArgc$Argv (len + 1, argv);
    argumentsC.setAppName (argv[0]);
    argumentsC.setAppModeString ("default");
    argumentsC.setBugAddress ("bug-swarm@swarm.org");
    argumentsC.setVersion ("0.0");
      
    argumentsC.addOption$key$arg$flags$doc$group ("myarg", (int) 'M', "argvalue", 0, "My Argument", 0);
    arguments = (Arguments) argumentsC.createEnd ();

    Globals.envC.setArguments (arguments);
    Globals.envC.createEnd ();
    
    System.out.println (Globals.env.arguments.getAppModeString ());
  }
}
