It's probably a good idea to name the file containing your source
using a file extension other than .adb or .ads (or .adp or .adc, in
case you take up extended features later). I'd use .ada

We had fun when the source was called Foo.ads, under NT one of the
split files ended up also called Foo.ads -- which overwrote our
original. Also, GNAT does *not* like files with upper-case letters in
the name at all!
