37 # argument, if specified, is the relative path that navigates
38 # from the submodule working tree to the superproject working tree.
40 # The output of the function is the origin URL of the submodule.
42 # The output will either be an absolute URL or filesystem path (if the
43 # superproject origin URL is an absolute URL or filesystem path,
44 # respectively) or a relative file system path (if the superproject
45 # origin URL is a relative file system path).
47 # When the output is a relative file system path, the path is either
