Right, this is understandably so. I would also not be interested if I
had already written my mi1 and mi2 parser. However, that doesn't mean
it's not the correct decision. Instead of writing a new parser, they
will get one for free, that they will never have to maintain. Doesn't
that sound nice?

These designated individuals either are busy or refuse to even discuss
the topic at hand. This is awfully unfriendly.

I believe that making GDB output XML would be trivial.

I am going to have to write an MI parser, if GDB refuses to simplfy it's
output. I have already been working on a project TGDB, and anyone that
wants to use it to base there front ends on GDB is welcome.

I care nothing about XML. As I say it over and over again. If XML is
outputted by GDB, it could be binary for all I care, NO parser has to be
written. The job has already been done.
I would not have to write a parser.
I would not have to write a library.
No one would.
Ever.
This is my point. I think that might have been my very first epilogue :)
BTW, if none of the front end writers or maintainers like this idea, I
will silently drop the issue. Personally, I thought many of the front
end writers would appreciate such a transparent protocol.
Thanks,
