The page at https://www.kernel.org/doc/man-pages/man_pages_other.html misses documentation for Arch Linx. I'd like to add the following. Arch Linux On Arch, [pacman](https://wiki.archlinux.org/index.php/Pacman) can be used to query the database to know which package a file in the file system belongs to. After finding out the package name, the Arch [Web Package Search](https://www.archlinux.org/packages/) can be used to find more about the package such as maintainer's contact details. If the package belongs to AUR (Arch User Repository), it can be searched [here](https://aur.archlinux.org/packages/)
