I found this project that can be helpful in getting a way to interface with pacman it uses PackageKit that has a alpm backend. I have been trying to get it to build without much success but it looks promising even just as an implementation example https://github.com/nemomobile/qmlpackagemanager

Or even using PackageKit-Qt directly can be possible https://github.com/hughsie/PackageKit-Qt

We'll keep the module name as Papyros.Software, but the title inside the app as well as the desktop file and executable name will need to be updated.
