# DisasBeautifier
Description
===========
Take `disas` ouput from gdb (either intel or at&t syntax), parse it and write it in output_file
Usage
=====
```sh
$ git clone [email protected]:Hackndo/disasbeautifier.git
$ cd disasbeautifier
$ chmod +x disasbeautifier.py
$ ./disasbeautifier.py input_file output_file
```
Example
=======
