+ * Processing a gitlink entry currently does nothing, since
+ * we do not recurse into the subproject.
+ *
+ * We *could* eventually add a flag that actually does that,
+ * which would involve:
+ *  - 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.
