+Keeping Up-to-date
+==================
+
+The best way to work with Gnulib is to check it out of CVS.
+Subscribing to the bug-gnulib@gnu.org mailing list will help you to
+plan when to update your local copy of Gnulib (which you use to
+maintain your software) from CVS. You can use "cvs update -dP" to
+synchronize.
+
+Sometimes, using an updated version of Gnulib will require you to use
+newer versions of GNU Automake or Autoconf. You may find it helpful
+to join the autotools-announce mailing list to be advised of such
+changes.
