Does anyone know whether the source to the programs in the Descent Manager project is available in any way? Not surprisingly, they've been all but abandoned by the developers, but there are still some bugs/lack of features I see in some that make a few of them much less capable than they should be (POLVIEW in particular).
If I actually had the code these problems would be very easy to get rid of... but as it stands the only option is to rewrite them and make them better. Either that or find other, often fairly number-crunching-heavy, ways to alter things. Not very appealing.
