53 # from the submodule working tree to the superproject working tree.
55 # The output of the function is the origin URL of the submodule.

58 # superproject origin URL is an absolute URL or filesystem path,
59 # respectively) or a relative file system path (if the superproject
60 # origin URL is a relative file system path).
