AE-targets without PPC Brow

[derek@cambridge.apple.com]

The following code fills in an ae desc with target info. It really defaults
the selection of the PPC browser, but I think it will still work if you remove the call to choose-process-dialog.

(defvar $local-target-name "Local")

(defconstant $your-ppc-type-name "XXXXep01") ; where XXXX is your creator type?

(defun parse-zone-str (str)
  ; parse strings of form "machine@zone or "machine:type@zone".
  (let ((start-type (position #\: str))
        (start-zone (position #\@ str)))
    (assert start-zone)
    (values
     (subseq str 0 (or start-type
                       start-zone))
     (if start-type
       (subseq str (1+ start-type) (if start-zone 
                                     (1- start-zone)
                                     (length str)))
       "")
     (subseq str (1+ start-zone) (length str)))))

(defun target-string-target-id (target-string target-id)
  ; Fill in a :TargetID POINTER with data from string.
  (assert (and (macptrp target-id) ; really needs to be a ptr not a handle
               (stringp target-string)))
