Well you don't have to worry about 8-letters and converting the file
names takes max 5 minutes on a user friendly OS.

I don't know how the .ada works, but sometimes you have to with in the
.adb and not the .ads to avoid circular dependance. But I guess you can
put the withs after the spec and the compiler will recognice this?

Anyway I still think it is clearer to have the .ads files for looking at
what a package provides. Besides you should also put your documentation
here that has to do with the usage of the procedures/functions. As to
big systems, do the packages become huge too or is it only that there a
lot of them?
