	<<Changes:
		<<7/8/06; 3:25:10 PM by DW
			<<Wake up the (new) fileSynch thread when an outline file is saved. We want the same instant-upload that we get in the folderWatcher in dotOpml.root. 
		<<8/10/05; 6:27:55 AM by DW
			<<Added code that pops all the hoists before saving, then restores them.
			<<Saving with something hoisted was a disaster. It only saves the hoisted material, the rest is lost. Reported on the opml-support list by David Wilkinson.
			<<http://groups.yahoo.com/group/opmlsupport/message/873
		<<6/13/05; 2:31:51 PM by DW
			<<If it's the OPML editor, call back, so we can do an immediate scan of the folder if it's in the www folder. Makes for quicker upstreaming. It's done within a try so there's no harm if it's not present.
		<<6/25/02; 1:06:47 AM by JES
			<<Set the title attribute of the window after it's been saved. The title attribute is used when creating bookmarks for disk-based outline files.
		<<3/26/02; 6:30:59 PM by JES
			<<If the window has an adrCloud attribute, add a <cloud> element to the OPML file.
			<<We make a local copy of the cloudData table, rename server to domain.
			<<If the window has a requestNotificationProcedure attribute, use its value for the registerProcedure cloudData sub-element.
		<<8/9/01; 1:11:41 AM by JES
			<<Preserve line endings for non-OPML files.
			<<On MacOS X, default to LF for the line ending.

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.
