-QPDF supports autoconf and libtool but does not use automake.  In
-addition, there is no header file generated by autoconf.  The only
-file distributed with the qpdf source distribution that is not a
-controlled file is "configure", and it is generated by just running
-"autoconf".  There is no need to run autoreconf, automake, autoheader,
-aclocal, or any other autotools programs beyond autoconf.
+QPDF supports autoconf and libtool but does not use automake.  The
+only files distributed with the qpdf source distribution that are not
+controlled are "configure", "libqpdf/qpdf/qpdf-config.h.in", and some
+documentation.  See above for the steps required to prepare a source
+distribution.
 
 A small handful of additional files have been taken from autotools
 programs.  These should probably be updated from time to time.
