Many packages (PKGBUILDs and associated files) comes from one of these
projects:
- Arch Linux
- Arch Linux ARM
- Arch Linux 32
- Aur (Arch User repository)

They typically come without a license, so while most of them seem to
be uncopyrightable due to their extreme simplicity and standardness,
this still creates some legal uncertaincy about their licensing.

Some packages also come from Hyperbola, and here there is also some
uncertaincy as the project added a CC0 license in its git repository
without adding any clear statement associated with it. We still need
to contact them to get more clarification on their packages licenses
for new contributions.

Several packages (and associated files) in this repository were
created from scratch, so they don't depend on other projects licensing
decisions.

And several contributors agreed to license their past contributions to
packages in this repository under the CC0 license:
- Andreas Grapentin
- bill-auger
- Denis 'GNUtoo' Carikli
- Freemor

As for patches, as they are combined with original project source code
they are under the same license than the original project.

All contributions to packages in this repository must be offered under
the CC0 license.
