reveal-in-osx-finder

Usage:

If M-x reveal-in-osx-finder is invoked in a file-associated buffer, it will open the folder enclosing the file in the OS X Finder. It will also highlight the file the buffer is associated with within the folder.
If M-x reveal-in-osx-finder is invoked in a dired buffer, it will open the current folder in the OS X Finder. It will also highlight the file at point if available.
If M-x reveal-in-osx-finder is invoked in a buffer not associated with a file, it will open the folder defined in the default-directory variable.
