33# The function takes at most 2 arguments. The first argument is the
35# URL that navigates to the submodule origin repo. When relative, this URL
36# is relative to the superproject origin URL repo. The second up_path
37# argument, if specified, is the relative path that navigates
38# from the submodule working tree to the superproject working tree.
39#
40# The output of the function is the origin URL of the submodule.
41#
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).
46#
47# When the output is a relative file system path, the path is either
48# relative to the submodule working tree, if up_path is specified, or to
49# the superproject working tree otherwise.
