A native QR code and barcode scanner application for Linux desktop, filling the gap of a missing desktop-friendly scanner tool.

CoBang can scan barcode, QR code from webcam or from static image. To be part of Linux desktop modernization, it is set to support Wayland (not XWayland), and only implement native GUI (no web crap).
