This directory contains a simple Qt application that creates a single "Hello,
Qt world!" label and a simple aspect that extends this application by a second
label.

---- Compilation ----

1) To compile the example, make sure that qmake will find the feature file
   acxx.prf via the evironment variable QMAKEFEATURES, for example:

     export QMAKEFEATURES=.

2) A call to qmake should then print:

       Project MESSAGE: AspectC++ Feature selected

   and create a platform specific Makefile, containing special rules, for
   example to use ag++ instead of g++.

3) Make sure, that you installed AspectC++ and that the environment variable
   PATH names the directory where ag++ and ac++ are located.

4) A subsequent call to make will then create the modified helloworld
   application. (Do not mind the warning about an unused parameter.)


---- Execution ----

Now run the application: 

       ./helloworld

You'll see two different labels, although a look into the source code reveals
that the application only creates a single lable.
