[REBOL] Re: [OT] Rebol vs Ruby

From: carlos:lorenz:g:mail at: 1-Nov-2005 8:39

Hi Gregg, I wonder if I can have your authorization to publish a translation to the Portuguese of this list of diffs at my FORUM at www.nobrenet.com/rebolbrasil<http://www.nobrenet.com/rebolbrasil> TIA 2005/10/31, Gregg Irwin <greggirwin-mindspring.com>:
