40# The function takes at most 2 arguments. The first argument is the
41# URL that navigates to the submodule origin repo. When relative, this URL
42# is relative to the superproject origin URL repo. The second up_path
43# argument, if specified, is the relative path that navigates
44# from the submodule working tree to the superproject working tree.
45#
46# The output of the function is the origin URL of the submodule.
47#
48# The output will either be an absolute URL or filesystem path (if the
49# superproject origin URL is an absolute URL or filesystem path,
50# respectively) or a relative file system path (if the superproject
51# origin URL is a relative file system path).
52#
53# When the output is a relative file system path, the path is either
54# relative to the submodule working tree, if up_path is specified, or to
55# the superproject working tree otherwise.
