According to the docs at

A directory is a package if:
1) it has a known suffix .app, .bundle, etc.
2) it has the bundle bit set
3) it has a known structure indicating its a bundle
I'm trying to construct some AppleScript (from my Cocoa app) to do
a Finder Get Info on an item.
tell application "Finder"
set macpath to POSIX file "%@" as text
open information window of %@ macpath
activate
end tell
I seem to need to specify "file" or "folder" in the second slot,
and AppleScript errors if I specify folder for a bundle.
So, given a directory, how can I tell if it is a bundle or not.
I've tried looking at the bundle bit, but in my /Applications
directory, only four .apps seemed to have it turn on.
I could implement 1, 2, and 3 above myself, but that would be hacky.
I could try and initialise a CFBundle or NSBundle with the
directory, but that is pretty nasty too.
Is there any easier or cleaner way to programmatically determine
whether a directory is a bundle or not?
If I do have to implement it myself, is there any way to get the
"known" suffixes?
