After tonights demo by Gilbert I decided to give parallel a try. I installed it on my Mint 10 (Linux) machine and my 10.6 Mac via Mac Ports. It works on the Mac and I haven't tried it under Linux yet. Anyhow I noticed the man pages are different. The Mac has a fuller man page than Linux.
First impression... It does what I want but I need to tweak my scripts.
