32# The function takes at most 2 arguments. The first argument is the
34# URL that navigates to the submodule origin repo. When relative, this URL
35# is relative to the superproject origin URL repo. The second up_path
36# argument, if specified, is the relative path that navigates
37# from the submodule working tree to the superproject working tree.
38#
39# The output of the function is the origin URL of the submodule.
40#
41# The output will either be an absolute URL or filesystem path (if the
42# superproject origin URL is an absolute URL or filesystem path,
43# respectively) or a relative file system path (if the superproject
44# origin URL is a relative file system path).
45#
46# When the output is a relative file system path, the path is either
47# relative to the submodule working tree, if up_path is specified, or to
48# the superproject working tree otherwise.
