+The utils folder includes a python script for downloading the latest ["manuf"](https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob_plain;f=manuf) file from Whireshark and convert it to the format understood by esp8266_deauther.

+The usage of the script is quite simple: `update_manuf.py [-h] [-o OUTPUT] [-u URL]` , e.g:
+```
+cd utils
+python update_manuf.py -o ../esp8266_deauther/oui.h
