Depends...

Existing Applications
======================

If running an existing applications (i.e. Jmol, JChemPaint...) you can run it 
like:

java -Dcdk.debugging=true -jar SomeJar.jar

which will fill the cdk.log

Additionally, you can do:

java -Dcdk.debugging=true -Dcdk.debug.stdout=true -jar SomeJar.jar

which will output the debugging info to STDOUT.


Custom Applications
====================

If referring to custom applications, then you also need to make sure to 
configure the LoggingTool. See the API for that class on how to do that.
It needs to be done only once.

In the CDK based applications, this is required to, which is, for example,
the reason why all JUnit classes nowadays CDKTest, which takes care of this.
