  Arnold, thank you. I think I have everything in
SF now. I added GPL
 notice to the package-info.java files and added INSTALL.txt,
 COPYING.txt, and LICENSE.txt.

 I appreciate your help.
          
 In Copying it's say: GPLv2 or at your option, any later version.
 License says GPLv3
 Don't know if that's a problem...
