On Adalog's component page (http://pro.wanadoo.fr/adalog/compo2.htm), you'll
find a small utility called Normalize that processes an Ada source and
removes comments, unnecessary spaces, and turns the whole text (except
strings) upper-case. This is precisely intended to make a diff on the
"semantic" part of the program. FWIW....

(I wrote this because of a lengthy discussion on this topic here some times
ago. It turned out that it was faster to write the utility than to discuss
about its desirability ;-)
