"""Arch Linux Package Manager (pacman) extension.

The extension provides a way to install, remove and search for packages in the archlinux.org \

database. If no search query is supplied, you have the option to do a system update. \

Otherwise albert will try to find for packages matching the filter. For more information about \

`pacman` please have a look at: https://wiki.archlinux.org/index.php/pacman
