+# (a) such a footer isn't present already (see the `meta' plugin's ``license''
+# facility) and (b) a file `license.html' is found (using the same rules as for
+# the sidebar plugin).
+#
+# The state which page's license text was gathered from which source is not
+# tracked, so you'll need a full wiki-rebuild if (b)'s files are changed.
+#
+# You can use wiki links in `license.html'.
