# Cursor theme licence

The pointer cursors in this directory are GNOME's **Adwaita** cursor
theme — the cursors GNOME Shell ships — bundled verbatim into the ltk
default theme. They are distributed by upstream under a choice of
licences:

- **Author:** the GNOME Project (Adwaita icon theme authors, 2002–2014)
- **Source:** <https://gitlab.gnome.org/GNOME/adwaita-icon-theme>
- **Licence:** **CC BY-SA 3.0 _or_ LGPL 3**, and CC BY-SA 4.0 for the
  newer assets — see below.

The licence is a disjunction: redistributing the cursors under **any
one** of the offered options satisfies it. ltk passes the choice
through unchanged.

- CC BY-SA 3.0 — <https://creativecommons.org/licenses/by-sa/3.0/>
- CC BY-SA 4.0 — <https://creativecommons.org/licenses/by-sa/4.0/>
- LGPL 3 — <https://www.gnu.org/licenses/lgpl-3.0.html>

## Required attribution

When redistributing this directory (or a binary that embeds these
cursor files), credit must be given to the GNOME Project and a link to
the chosen licence must be reachable. The wording is flexible — any of
the following satisfies the obligation:

> Cursors by the [GNOME Project](https://www.gnome.org), Adwaita cursor
> theme, CC BY-SA 3.0 / LGPL 3.

> Pointer cursors: © the GNOME Project, Adwaita, distributed under
> CC BY-SA 3.0 (https://creativecommons.org/licenses/by-sa/3.0/).

Upstream notes that, for attribution, "using 'GNOME Project' is enough".

The full Debian-style attribution lives in the top-level
[`debian/copyright`](../../../debian/copyright) of the `ltk` source
tree under the `Files: themes/default/cursors/*` paragraph.

## Modifications

The cursor files in this directory are **unmodified** copies of the
upstream Adwaita XCursor files (the alias symlinks are part of the
upstream theme). No content changes have been made, so there is nothing
to declare under the ShareAlike "indicate if changes were made" clause.
Anyone needing a pristine copy can also fetch it from the upstream
`adwaita-icon-theme` release.

## How licensing applies to the rest of the theme

The rest of the default theme is licensed separately: branding artwork,
app icons and the unknown-app fallback are original Liberux Labs work
under `LGPL-2.1-only`, and the catalogue glyphs under
`themes/default/icons/catalogue/` are Streamline's under CC BY 4.0 (see
that directory's `LICENSE.md`). Forks should preserve the split:
re-license your own artwork freely, but the contents of this `cursors/`
directory remain the GNOME Project's under the terms above.
