	<<This script changes your default upstream server to the new server at Radio.xmlStorageSystem.Com.
	<<Radio.xmlStorageSystem.Com will be the default server for all Radio UserLand 7.1 installations.
	<<The script first moves your weblog files into the www/system/upstream folder, and updates your weblog prefs.
	<<Next, it registers with the new xmlStorageSystem server, and creates a #upstream.xml file which points at your new account. The original #upstream.xml is backed up to #upstream.bkp.
	<<Last, it invalidates the upstream cache for all the files in the upstream folder, causing the files to be upstreamed to the new server.

This listing is for code that runs in the OPML Editor environment. I created these listings because I wanted the search engines to index it, so that when I want to look up something in my codebase I don't have to use the much slower search functionality in my object database. Dave Winer.
