+* Installing changes from gnulib
+Some of the files in Emacs are copied from gnulib.  To synchronize
+these files from the version of gnulib that you have checked out into
+a sibling directory of your branch, type "make sync-from-gnulib"; this
+will check out the latest version of gnulib if there is no sibling
+directory already.  It is a good idea to run "bzr status" afterwards,
+so that if a gnulib module added a file, you can record the new file
+using "bzr add".  After synchronizing from gnulib, do a "make" in the
+usual way.
+
+To change the set of gnulib modules, change the GNULIB_MODULES
+variable in the top-level Makefile.in, and then run:
+
+  ./config.status
+  make sync-from-gnulib
+  bzr status
+
+The last command will mention files that may need to be added using
+"bzr add".  If you remove a gnulib module, or if a gnulib module
+removes a file, then remove the corresponding files by hand.
