Skip initialization message

Hi,

when I start RapidMiner with "java -cp lib/rapidminer.jar:./ ..." I get the initialization debug message:

G Jun 22, 2009 11:38:15 AM: Property rapidminer.home is not set. Guessing.
G Jun 22, 2009 11:38:15 AM: Trying parent directory of YYY/../lib/rapidminer.jar'...gotcha!
G Jun 22, 2009 11:38:15 AM: Trying base directory of classes (build) 'YYY'...gotcha!

Is there a way to skip this output?

Best,
