First cut is checked into SVN. If no problems, I'll add a couple more features sometime. I especially want to add localization support for GUI developers. Thanks, /dev/mrg PS. Ari, I've never used ROP and I think you are the big ROP guy. If you get a chance sometime, please test it a bit with ROP and let me know if there are issues. Thanks!
