+Subject: [PATCH] Support building with Doxygen 1.9.7
+
+Doxygen 1.9.7 made some changes whereby some method definitions are now
+defined in separate XML files, with a "refid" that links to them.  In
+order to support this, we need to follow these "refids" to pick up the
+method definition from the separate group XML files.
