I think your final implementation is likely to be using NSWorkspace,
as others have suggested, not NSAppleScript.
However, for the benefit of the archives, I'd like to point out that
the construct you have below is very unsafe.
If the path has any non-MacRoman characters in it, the AppleScript
will fail entirely.
If the path has QUOTES in it, then the result is undefined--the
user's path name will end up being interpreted as AppleScript
commands, which in the wrong hands could be used as an exploit. You
don't want your app to be known for having a security hole :(
The workaround is to represent the path as ‹‹utf8›› data.

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?
