How does having multiple directories make that easier?

Hmm. In emacs, I pull up the whole directory, then search in the

But actually, to navigate Ada source, I don't tend to use file names;
I use Ada names, and let Emacs figure out where the files are.

File names that mimic the package tree are better than directories
that mimic the package tree, in my opinion. I haven't heard any solid
evidence here to contradict that.
