I am not going to waste time arguing with the maintainers and chasing
after them. I have a debugger, it has lots of users and a big
installed base that goes back many years. So long as they can get it
and use it, things are cool. Putting it in Linux is actually more of
a pain than just doing what I have been over the years and maintaining
it alongside linux.

Each merge cycle it will be submitted for the linux community, but
like I said, I am not wasting time with folks who are not my customers
and or really not that interested in it.

I already played the bait and switch game with Ingo once before and I
did a lot a work and it was ignored, so he can waste someone else's
time. Linux is only as good as the people maintaining it.

Jeff
