[arch-general] Where does /usr/bin/uwsgi come from?

Hello all, I've got sth. strange: I wanted to install the "uwsgi" package, but the binray is already installed. "pacman -Qo uwsgi" results in "No package owns /usr/bin/uwsgi" (German: "Kein Paket besitzt /usr/bin/uwsgi"). So, why is it on my laptop? I'd guess it's probably been installed at some time with apache httpd but has been removed later, but don't know. Anybody knows about such an issue? Kind regards Peter
