The best way to update is to move the existing Jaseck's Collection and
More Bud's Frames to the Left panel, hit "Generate" to remove the
corresponding HTMLs, then delete Jaseck and More Bud's from the Left
panel.  Then you can use "File/Import Specs..." to read the new XMLs.
They should then appear in the Left panel and you can move them back
to the Right as you wish.
