## 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
+## tools instead of using this. Note that if eg configure.ac
## 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.
