Thanks. I updated the package README to indicate how /etc/openhab.conf
is used.

Here is the latest interation for comments/feedback. I'd still like to
break out to /var/lib/openhab/{conf,userdata} for 
${WRKDIST}/{conf,userdata} but getting the fake framework and PLIST was
still proving a challenge. I'm also working on fixing restart (need
seatbelts around start/stop since the wrapper scripts don't produce the
pid until they complete). Everything else should be updated based on
feedback.

Thanks again for all the help.
