Source: qr-tools
Version: 2.1-2
Severity: minor
Tags: upstream patch
Attached is a patch to port qr-tools from PyQt5 to PyQt6.
I noticed upstream is not active anymore, so I don't think there is
anywhere to forward it. In the absence of an active upstream, I think
it'd be meaningful to carry it to the Debian package.
Thank you for maintaining qr-tools! I've found it to be quite useful.
It's one of the last Qt5 tools on my system, and I started getting
worried about its inclusion in Debian, hence this patch :) HTH!
Regards,
Faidon
