| # URL that navigates to the submodule origin repo. When relative, this URL |
| # is relative to the superproject origin URL repo. The second up_path |
| # argument, if specified, is the relative path that navigates |
| # from the submodule working tree to the superproject working tree. |
| # |
| # The output of the function is the origin URL of the submodule. |
| # |
| # The output will either be an absolute URL or filesystem path (if the |
| # superproject origin URL is an absolute URL or filesystem path, |
| # respectively) or a relative file system path (if the superproject |
| # origin URL is a relative file system path). |
| # |
| # When the output is a relative file system path, the path is either |
| # relative to the submodule working tree, if up_path is specified, or to |
| # the superproject working tree otherwise. |
