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

51 # the superproject working tree otherwise.
