I tried this for each of the components, yet everything still wound up in
grouper-api_*.log. A little more investigation yielded that when
rebuilding the components with "ant dist", is copied from
the grouper-api conf dir.

[copy] Copying /home/grouper/grouper/grouper-api/conf/

[copy] Copying /home/grouper/grouper/grouper-api/conf/

So at least that explains why its all going to the same logfile. It doesn't
seem to use webapp/appName/WEB-INF/classes/ in the build (or
it's overwritten if it does). Or am I building/deploying this wrong? I think
what I'm doing is consistent with the general overlay process, no?
