+   This file shows a simple way to fuzz command-line parameters with stock
+   afl-fuzz. To use, add:
+
+   #include "/path/to/argv-fuzz-inl.h"
+
+   ...to the file containing main(), ideally placing it after all the 
+   standard includes. Next, put AFL_INIT_ARGV(); near the very beginning of
+   main().
+
+   This will cause the program to read NUL-delimited input from stdin and
+   put it in argv[]. Two subsequent NULs terminate the array. Empty
+   params are encoded as a lone 0x02. Lone 0x02 can't be generated, but
+   that shouldn't matter in real life.
+
+   If you would like to always preserve argv[0], use this instead:
+   AFL_INIT_SET0("prog_name");
