 Notes about the native targets of the Xcode projects:
-    * the Xcode projects refer to the tcl and tk source dirs with a relative
-	path of ../../tcl and ../../tk to the project location, if your source
-	directories are named differently you'll need to enter the correct path
-	in the info panel of the 'Tcl Sources' and 'Tk Sources' groups.
+    * the Xcode 2 project refers to the toplevel tcl and tk source dirs through
+	the TCL_SRCROOT and TK_SRCROOT user build settings, by default these are
+	set to the project-relative paths '../../tcl' and '../../tk', if your
+	source directories are named differently, e.g. '../../tcl8.5', you'll
+	need to manually change the TCL_SRCROOT and TK_SRCROOT settings by
+	editing your ${USER}.pbxuser file (located inside the Wish.xcodeproj
+	bundle directory) with a text editor.
     * XCode 1.5 has a bug that causes Fix&Continue and the Build menu items
 	Compile/Preprocess/ShowAssembly to fail in presence of relative paths to
 	source files, as a workaround change the Path Type of the 'Tcl Sources'
 	and 'Tk Sources' groups to 'Absolute Path' in the groups' Info panel.
