[Coco] NitrOS-9 boot configuration tool

[David Gettle]

Sounds like a very useful application when you get it completed, will you
be including a way to update the dependencies in the event additional
changes to NitrOS9 are made in the future? ie. new storage media devices or
the like?

Also would you please include me in the list to get a copy of the text for
module dependency, I would like to have it for reference also, I have the
original OS-9 dependencies in the manuals, but have not worked with that in
years, and have not created a working boot disk in years either, (quite
frankly I don't remember all the dependencies any more it's been too long
since I've worked with it).
or better yet how about posting it for download on the NitrOS9 download
site so everyone in the community can have a copy if they want, as it would
be a good reference for all of us. It may even open a way to streamline the
OS even more.
