Dangling symlinks
  On many OSs, you can have 'dangling' symlinks:
    $ ln -s nada dangling
    $ ls -l nada realfile dangling
    -rw-r--r--    1 reegen  reegen  151 Sep 17 10:00 realfile 
    lrwxrwxrwx    1 reegen  reegen   10 Sep 17 10:00 dangling -> nada
    ls: nada: No such file or directory
    $ perl -e '$_="realfile"; print "$_ Exists\n" if -e $_'
    realfile Exists
    $ perl -e '$_="nada"; print "$_ Exists\n" if -e $_'
    $ perl -e '$_="dangling"; print "$_ Exists\n" if -e $_'
