Correct but irrelevant.  If you want to program using QtAda, you're
going to have to link your program against both QtAda and the
underlying Qt (and possibly other libraries too), therefore you must
consider how the licenses of both Qt and QtAda (and the other
libraries, if any) affect your program.  Qt is under LGPL at no cost.
QtAda uses the classical dual-licensing scheme: GPL at no cost, GMGPL
at extra cost.
