    Postprocessor libraries can be passed to afl-fuzz to perform final cleanup
    of any mutated test cases - for example, to fix up checksums in PNG files.
 
    Please heed the following warnings:
 
    1) In almost all cases, it is more productive to comment out checksum logic
       in the targeted binary (as shown in ../libpng_no_checksum/). One possible
       exception is the process of fuzzing binary-only software in QEMU mode.
 
-   2) Use of postprocessors for anything other than checksums is questionable
+   2) The use of postprocessors for anything other than checksums is questionable
       and may cause more harm than good. AFL is normally pretty good about
       dealing with length fields, magic values, etc.

+   3) Postprocessors that do anything non-trivial must be extremely robust to
       gracefully handle malformed data and other error conditions - otherwise,
       they will crash and take afl-fuzz down with them. Be wary of reading past
       *len and of integer overflows when calculating file offsets.
 
    In other words, THIS IS PROBABLY NOT WHAT YOU WANT - unless you really,
    honestly know what you're doing =)
 
    With that out of the way: the postprocessor library is passed to afl-fuzz
    via AFL_POST_LIBRARY. The library must be compiled with:
 
@@ skipping 71 matching lines @@
   /* Insert the new header. */
 
   memcpy(new_buf, HEADER, strlen(HEADER));
 
   /* Return modified buffer. No need to update *len in this particular case,
      as we're not changing it. */
 
   return new_buf;
