Thanks, that works. But the docs are confusing -- it gives the 
impression that "sharedLog" is something associated with the 
default logger -- so I would expect the above to work with just 
the plain log() call to invoke the default logger. But it seems 
like I am just creating a new logger and using that by saying 
"sharedLog.log()".

 From the doc:

The default Logger will by default log to stderr and has a 
default LogLevel of LogLevel.all. The default Logger can be 
accessed by using the property called sharedLog. This property a 
reference to the current default Logger. This reference can be 
used to assign a new default Logger.

sharedLog = new FileLogger("New_Default_Log_File.log");
