You can use a pathname relative to the home: logical host.

? (probe-file "home:.profile")
#P"/Users/rme/.profile"

Or, use a tilde:

? (probe-file "~")
#P"/Users/rme/"

? (probe-file "~/foo")
#P"/Users/rme/foo"

(tilde expansion was added a few months ago.)

Well, it's not like the app bundle is sacred or anything.  It can be a  
pain to deal with files in it because the Finder treats the .app as a  
unified thing (modulo Show Package Contents, of course).

However, it's not exactly clear yet what should end up in the app  
wrapper.  What about sources?  The interface databases?  Saved  
images?  This stuff still needs to be worked out.

It might be easiest just to pick some place in the home directory, and  
use that.  Maybe set up a logical pathname host for it if that would  
be convenient, e.g.

(setf (logical-pathname-translations "stuff")
     '(("**;*.*.*" "/Users/rme/stuff/")))
