  3) Ask on the velocity-user list.  This is a great source of support information.
     To join, read http://jakarta.apache.org/site/mail.html and then follow the 
     link at the bottom to join the lists.
  
  logger_example
  ------------
  This 'toy' example shows how to use the Velocity logger interface
  to have any class function as a logging facility.  
  
  To run :
  
  ./logger_example.sh
