On the general subject of a launch script, I've attached a Launch.py
replacement that I've been using. I'm not using it much anymore, since
I'm not using Webware (at least this version of Webware), but it's
worked okay in the past (maybe the attempt to kill existing app servers
is too aggressive, though). I don't have time to integrate it, but here
it is for someone who is interested...
