>From what I could tell, this worked, but I was also to have a user-
friendly customization interface when a user, say, clicked customoize
corext-enlistments.  I'd like a prompt for the symbol-name, and the
individual property list values: branch, drive, and path.  It seems
that to acheive something like this, I'd need to just make them
alists....
