Well? Is there a new format yet?
http://developer.apple.com/cgi-bin/search.pl?&q=applesingle
doesn't illuminate even the old format.
And while we're at it: is there documentation somewhere
as to the format of a ._ file, as referred to here:
http://developer.apple.com/documentation/MacOSX/Conceptual/SystemOverview/Finder/chapter_9_section_6.html
and is there an official name for these ._ files? Are they simply the other half of appledouble?
I'm putting together a spec for an extended rsync, which I will float here. I wonder if the Tiger rsync will satisfy it.
Thanks
Dave

If you use AppleSingle instead of inventing your own encoding, then you'll know that your files will continue to work even if Apple starts using metadata you weren't saving.
