+// Disable the footer for the HTML render.  The footer for HTML is not well
+// documented in Asciidoc, but it appears to insert a line "Last updated <date>"
+// at the very bottom of the HTML where the <date> is the timestamp of the
+// "syclbase.adoc" file.  This date is confusing because it might be quite a bit
+// older than the last modification to the specification.  We already have the
+// specification date in the HTML header, which shows the timestamp when the
+// specification was built from Asciidoc sources.
+//
+// Note that we *do* want a footer in the PDF render, which contains completely
+// different content.  The PDF footer shows the page number and the current
+// chapter.
