+## Helper script for those building Emacs from bzr without autoconf etc.
+## This installs some pre-generated versions of the automatically
+## generated files.  It is highly recommended to install the necessary
+## tools instead of using this.  Note that if eg configure.in
+## is updated, the next time you run make it will attempt to
+## regenerate configure and will fail if you do not have the required
+## tools.  You will have to run this script again.
