## Installation

### with pip
Eventually, install with `pip install drawbridge`, maybe.

For now, clone the repo, navigate to it, and run `pip install .`. You'll need a Linux system for nfqueue.

## Examples

See the examples directory for a WebSocket example.

```python
from drawbridge import DrawBridge

def my_packet_handler(raw_packet):
    # do things to the raw packet, like
    #   from scapy.all import *
    #   pkt = IP(raw_packet)
    #   ...
    #   return bytes(pkt)
    return raw_packet

db = DrawBridge()
db.add_queue(my_packet_handler, src_port=80)
db.run()
```
