+autoconf files
+--------------
+
+If you wish to change the `configure' script or its related files,
+you'll need to first install GNU m4 and GNU autoconf. Mmh is currently
+using a minimum of autoconf 2.61.
+
+Most of the configure-related files are automatically generated. The
+only files you should need to manually edit are `acconfig.h' and
+`configure.ac'. Don't, for instance, edit `config.h.in'. Though it is
+an input file from the point of view of the users (and the configure
+script) it is an output file from the point of view of the developers
+(and the autoconf script).
+
+Note that the automatically generated autoconf files (such as
+`config.h.in', `stamp-h.in', and `configure'), are NOT kept in the
+version control system. Thus, when you check out the source tree,
+you need to run the `autogen.sh' script before you can build anything:
+
+ % ./autogen.sh
