49# The function takes at most 2 arguments. The first argument is the
50# URL that navigates to the submodule origin repo. When relative, this URL
51# is relative to the superproject origin URL repo. The second up_path
52# argument, if specified, is the relative path that navigates
53# from the submodule working tree to the superproject working tree.
54#
55# The output of the function is the origin URL of the submodule.
56#
57# The output will either be an absolute URL or filesystem path (if the
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).
61#
62# When the output is a relative file system path, the path is either
63# relative to the submodule working tree, if up_path is specified, or to
64# the superproject working tree otherwise.
