+Note that an important property of the basewiki is that it should be
+self-contained. That means that the pages listed above cannot link
+to pages outside the basewiki. Ikiwiki's test suite checks that the
+basewiki is self-contained, and from time to time links have to be
+removed (or replaced with `iki` [[shortcuts]]) to keep this invariant.
