-   american fuzzy lop++ - postprocessor library example

-   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) 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:
-
-     gcc -shared -Wall -O3 post_library.so.c -o post_library.so
-
-   AFL will call the afl_postprocess() function for every mutated output buffer.
-   From there, you have three choices:
-
-   1) If you don't want to modify the test case, simply set `*out_buf = in_buf`
-      and return the original `len`.
-
-   2) If you want to skip this test case altogether and have AFL generate a
-      new one, return 0 or set `*out_buf = NULL`.
-      Use this sparingly - it's faster than running the target program
-      with patently useless inputs, but still wastes CPU time.
-
-   3) If you want to modify the test case, allocate an appropriately-sized
-      buffer, move the data into that buffer, make the necessary changes, and
-      then return the new pointer as out_buf. Return an appropriate len
-   afterwards.
-
-      Note that the buffer will *not* be freed for you. To avoid memory leaks,
-      you need to free it or reuse it on subsequent calls (as shown below).
-
-      *** Feel free to reuse the original 'in_buf' BUFFER and return it. ***
-
-    Aight. The example below shows a simple postprocessor that tries to make
-    sure that all input files start with "GIF89a".
-
-    PS. If you don't like C, you can try out the unix-based wrapper from
-    Ben Nagy instead: https://github.com/bnagy/aflfix
