+   If you reading this part of these instructions in order to generate
+   a version of the patch for a new release, you'll need to pick a
+   version of the patch from some prior release to use as a starting
+   point.  In general, the patch corresponding to the most recent
+   prior release will be the best starting point.

    All hunks should have applied successfully with no offset or fuzz.
    If all succeeded but some were offset or had fuzz, the patch will be
    regenerated at the end of this stage.
 
+   Note that two of the files which the patch attempts to update
+   (configure and config.h.in) are generated automatically.  When
+   generating a new patch, the old version of the patch may not apply
+   correctly to these files, but that's ok so long as the patch does
+   apply correctly to the source files from which these files are
+   generated.  The steps below will regenerate these files.
