     "qBittorrent is a BitTorrent client programmed in C++/Qt that uses
libtorrent (sometimes called libtorrent-rasterbar) by Arvid Norberg.

It aims to be a good alternative to all other BitTorrent clients out there.
qBittorrent is fast, stable and provides unicode support as well as many
features.")

I am trying to make a patch to fix https://github.com/qbittorrent/qBittorrent/issues/16139 which is caused by us using an unsupported python version -> How can i specify that the package is only allowed to use python 3.2 <= 3.5.0 ?
