I don't mean for the running application, I mean for an application

that can do this, but cannot find it anywhere. So how do I go about
detecting which chip architectures an application will run on?
In case I'm being too ambiguous, I mean Intel/PPC/Universal.
The "lipo" tool is most often used to create Universal Binaries, but
it also has an -info option:
Sherm-Pendleys-Computer:~ sherm$ lipo Applications/Aquamacs\
Emacs.app/Contents/MacOS/Aquamacs\ Emacs -info
Architectures in the fat file: Applications/Aquamacs Emacs.app/
Contents/MacOS/Aquamacs Emacs are: i386 ppc
The "file" command-line tool will also do this. For instance:
Sherm-Pendleys-Computer:~ sherm$ file Applications/Aquamacs\
Emacs.app/Contents/MacOS/Aquamacs\ Emacs
Applications/Aquamacs Emacs.app/Contents/MacOS/Aquamacs Emacs: Mach-O
fat file with 2 architectures
Applications/Aquamacs Emacs.app/Contents/MacOS/Aquamacs Emacs (for
architecture i386): Mach-O executable i386
Applications/Aquamacs Emacs.app/Contents/MacOS/Aquamacs Emacs (for
architecture ppc): Mach-O executable ppc
