CAN USB ↔ SocketCAN Bridge

A real-time bridge utility between USB CAN Analyzer and a SocketCAN interface written in C++20.

---

🔌 Features

• Bidirectional forwarding between USB-CAN (serial) and SocketCAN
• Command-line configurable
• Thread-safe, real-time friendly
• CAN 2.0 and CAN FD support

---

🧰 Requirements

• Linux with CAN and serial support
• libstdc++ with C++20
• argparse C++ header (or replace with manual parsing)
