-# afl-frida - faster fuzzing of binary-only libraries
-
-## Introduction
-
-afl-frida is an example skeleton file which can easily be used to fuzz
-a closed source library.
-
-It requires less memory and is x5-10 faster than qemu_mode but does not
-provide interesting features like compcov or cmplog.
-
-## How-to
-
-### Modify afl-frida.c
-
-Read and modify afl-frida.c then `make`.
-To adapt afl-frida.c to your needs, read the header of the file and then
-search and edit the `STEP 1`, `STEP 2` and `STEP 3` locations.
-
-### Fuzzing
-
-Example (after modifying afl-frida.c to your needs and compile it):
-```
-LD_LIBRARY_PATH=/path/to/the/target/library/ afl-fuzz -i in -o out -- ./afl-frida
-```
-(or even remote via afl-network-proxy).
-
-# Speed and stability
-
-The speed is very good, about x12 of fork() qemu_mode.
-However the stability is low. Reason is currently unknown.
-
-# Background
-
-This code is copied for a larger part from https://github.com/meme/hotwax

- HOW-TO
- ======
-
- You only need to change the following:
-
- 1. set the defines and function call parameters.
- 2. dl load the library you want to fuzz, lookup the functions you need
- and setup the calls to these.
- 3. in the while loop you call the functions in the necessary order -
- incl the cleanup. the cleanup is important!
-
- Just look these steps up in the code, look for "// STEP x:"
