Any way to stop SVNBootstrapper externals messages

Hiya,

I was wondering if there is a way to stop the constant SVNBootstrapper 
messages that get written to the cruisecontrol.log file.  Every few minutes 
CruiseControl appears to check the externals for the bootstrapper and writes 
the following entries to the cruisecontrol.log file.

2012-11-24 20:54:05,688 [Thread-629] INFO  SVNBootstrapper  - Fetching 
external item into 'lib/cpy/copy1.cpy'
2012-11-24 20:54:05,712 [Thread-629] INFO  SVNBootstrapper  - External at 
revision 123456.

2012-11-24 20:54:05,877 [Thread-629] INFO  SVNBootstrapper  - External at 
revision 123456.

My cruisecontrol.log files seem to mainly consist of these messages.  Can I 
switch them off somehow?

Steve Murphy
