31 * Processing a gitlink entry currently does nothing, since
32 * we do not recurse into the subproject.
34 * We *could* eventually add a flag that actually does that,
35 * which would involve:
36 * - is the subproject actually checked out?
37 * - if so, see if the subproject has already been added
38 * to the alternates list, and add it if not.
39 * - process the commit (or tag) the gitlink points to
42 * However, it's unclear whether there is really ever any
43 * reason to see superprojects and subprojects as such a
44 * "unified" object pool (potentially resulting in a totally
45 * humongous pack - avoiding which was the whole point of
46 * having gitlinks in the first place!).
48 * So for now, there is just a note that we *could* follow
49 * the link, and how to do it. Whether it necessarily makes
50 * any sense what-so-ever to ever do that is another issue.
