<% title # Logging aspect %>
<p class="j">This aspect allows logging some diagnostic information with minimum efforts. 
All you need to do is to decorate your class with the Log attribute. 
If you have a class hierarchy you can decorate only your base class. 
Diagnostic information will be logged for all virtual and abstract members 
of your abstract class.</p>
