For our Xcode-based builds, we do something similar, except we use log4j 
straight w/o any of the NSLog stuff. For our strictly Eclipse/WOLips 
projects, we just add our log4j.properties to the classes.include file and 
WOLips puts it on the classpath for us. However, we just recently started 
integrating project Wonder, and we're now using their log4j setup (which 
includes a component where you can dynamically change logging levels at 
runtime).
