It still has a little ways to go to be ready for mainstream use, but it's already running a lot, and I hope you'll consider it for the future since it simplifies things A LOT when you can just write to POSIX instead of having to come up with abstraction layers that cater to Windows' brokenness. > > Well thank you for being honest.

I hope we can get this thread away from accusing and attacking people and on to doing productive things to make the software better. Rich
