I don't suppose anyone associated with the project is reading this
news group, are they? Don't be shy! :-)

I find it quite easy to believe that some 800K SLOC of Ada could be
"reused" as is; I have a LOT of packages that I reuse all the time,
and I can believe that a large system might be, say, 80% existing
utilities (database management, windowing package, etc.) and 20% glue.

On the other hand, I can also picture "enhancing" a large portion of not
necessarily directly reusable code, making many changes in many places.
Ada makes THAT relatively easy, too.

SO - unless someone on the project can comment, let's admit that we're
all guessing, shall we? :-)
