- * Processing a gitlink entry currently does nothing, since

- *  - is the subproject actually checked out?
- *  - if so, see if the subproject has already been added
- *    to the alternates list, and add it if not.
- *  - process the commit (or tag) the gitlink points to
- *    recursively.
- *
- * However, it's unclear whether there is really ever any
- * reason to see superprojects and subprojects as such a
- * "unified" object pool (potentially resulting in a totally
- * humongous pack - avoiding which was the whole point of
- * having gitlinks in the first place!).
- *
- * So for now, there is just a note that we *could* follow
- * the link, and how to do it. Whether it necessarily makes
- * any sense what-so-ever to ever do that is another issue.
