=============== Diff against Network-mt.243 ===============
Item was changed:
----- Method: FileUrl>>privateInitializeFromText:relativeTo: (in category 'private-initialization') -----
privateInitializeFromText: pathString relativeTo: aUrl
"<pathString> should be a filesystem path.
This url is adjusted to be aUrl + the path."
