My reasoning was pragmatic: I was launching Tomcat via a remote ssh
shell, so the stderr and stdout output was lost.  I imagine this case
will be common enough that I'm acting on the assumption that all
messages, including exceptions, should go to the appropriate log file,
not to the console.  This also means that everything can be configured
using server.xml -- no need for command-line fidgeting.

Perhaps someone who doesn't agree with us can use the "level" variable
(Logger.INFORMATION / Logger.WARNING / Logger.ERROR) to send ERRORs to
one file and INFORMATIONs to another, or something like that.
