How to find the residing directory of a OS X application package - programmatically

Question

I have a OS X application as a .app package which can reside in any arbitrary location in the filesystem. Is there a way to find the current path of the package programmatic

Building off the argv[0] version above, you can also get the path from:

    NSArray* arguments = [[NSProcessInfo processInfo] arguments];

    NSString* exe = [args objectAtIndex:0];

from init or applicationDidFinishLaunching
