+Building from version control
+=============================
+
+If you check out qpdf from version control, you will not have the
+files that are generated by autoconf.  If you are not changing these
+files, you can grab them from a source distribution or create them
+from a system that has autoconf.  To create them from scratch, run
+./autogen.sh on a system that has autoconf installed.  Once you have
+them, you can run make CLEAN=1 autofiles.zip.  This will create an
+autofiles.zip that you can extract on top of a fresh checkout.
