status (meta):
    Update meta data files for those that have changed.
    Check for changed pads by looking at revisions & comparing to existing


design decisions...
ok based on the fact that only the txt file is pushable (via setText)
it makes sense to give this file "primacy" ... ie to put the other forms
(html, diff.html) in a special place (if created at all). Otherwise this
complicates the "syncing" idea....
