   * Add patch 17_xmodmap_manpage.diff to make xmodmap(1) refer to
     /usr/share/X11/XKeysymDB instead of /usr/lib/X11/XKeysymDB
     (closes: #394077).  Thanks, Joachim Breitner!
+  * Document each app's build-dependencies in debian/control for reference.
 
   [ Brice Goglin ]
   * Restore Depends: on cpp (got lost during modularization)
     since xrdb needs it to process .Xdefaults.
     Thanks Marcus C. Gottwald (closes: #413298).
