	<<Changes:
		<<2/8/03; 7:21:48 PM by JES
			<<Fix a bug which could cause databases to be skipped on MacOS X if their type/creator codes are not set.
		<<7/30/02; 11:55:33 PM by JES
			<<Released for Frontier with the flReverse optional parameter. Brings this verb into synch with the Radio version. Also, the Frontier version was calling frontier.getFilePath instead of window.getFile, which fails to produce the correct path for Frontier.root if the frontmost window is owned by another database.
		<<10/26/00 at 7:06:18 PM by PBS
			<<New optional parameter: flReverse. It's false by default, preserving current behavior. If true, visit in reverse order. This is needed when you're closing databases.
		<<12/15/1999; 3:28:07 PM by AR
			<<Visit all open databases including Frontier.root and call the script pointed to by adrvisitproc for every database. That script should take a single parameter, the file path of the database.

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.
