| This program generates gnuplot images from afl-fuzz output data. Usage: |
| |
| $0 afl_state_dir graph_output_dir |
| |
| The afl_state_dir parameter should point to an existing state directory for any |
| active or stopped instance of afl-fuzz; while graph_output_dir should point to |
| an empty directory where this tool can write the resulting plots to. |
| |
| The program will put index.html and three PNG images in the output directory; |
| you should be able to view it with any web browser of your choice. |
