atomically:NO is bad.

I don’t like rewriting Info.plist at all, actually. Can we stuff the things we
need into some other file that isn’t used for any purpose other than the our
own?

[sail, 2012/02/08 06:12:51]

Unfortunately I think there are some standard Info.plist entries that we'll have
to customize at publish time. For example:
  - bundle identifier
  - bundle display name
  - document types/handlers

This would almost certainly be better if you built up the staging app in the
same directory where it’s supposed to wind up, but as a dot-file or something.
Then you can just move it into place instead of having to copy it.

[sail, 2012/02/08 06:12:51]

Ahh, I didn't realize I was doing a copy. I think I could do a move from the tmp
directory. There should be a function that lets you create a temp folder on the
same volume as the target folder. Looking...

+
+  // Update the app's plist and icon in a temp directory. This works around
+  // a Finder bug where the app's icon doesn't properly update.
