+The shell script `autogen.sh' generates 'configure' and other files by
+running the GNU build tools autoconf and automake, which in turn use
+GNU m4 and Perl. If you want to use it, you will need to install
+recent versions of these build tools. This should be needed only if
+you edit files like `configure.ac' that specify Emacs's autobuild
+procedure.
The file `Makefile.in' is a template used by `configure' to create
`Makefile'.
