builds the software in an Arch Linux container,
publishes the resulting install tree as a .tar.zst asset on a GitHub release of this repository (tag <pkgname>-<version>),
updates the PKGBUILD (pkgver/pkgrel/sha256sums), test-builds it with makepkg and regenerates .SRCINFO,
commits the changes back to this repository, and
pushes PKGBUILD + .SRCINFO to the AUR.

The AUR packages themselves only download the prebuilt asset from step 2, so users don't need any build dependencies.

Packages

Package	Upstream	AUR
`timetable-bin`	ostfriese4/untis — "Timetable", a GTK4 + LibAdwaita client for WebUntis	timetable-bin

Setup (one-time)

Create an AUR account and add an SSH public key to it (AUR account settings).
Add the matching private key as a repository secret named AUR_SSH_PRIVATE_KEY (Settings → Secrets and variables → Actions → New repository secret).
Optionally set the repository variables AUR_GIT_NAME and AUR_GIT_EMAIL to control the commit identity used on the AUR (defaults: Felitendo / 95575686+Felitendo@users.noreply.github.com).

The first push to ssh://aur@aur.archlinux.org/<pkgname>.git creates the AUR package automatically.

Adding a package

Create a new directory named after the AUR package containing:

PKGBUILD — sources the prebuilt asset from https://github.com/Felitendo/PKGBUILDS/releases/download/<pkgname>-<pkgver>/<pkgname>-<pkgver>.tar.zst. pkgver, pkgrel and sha256sums are maintained by CI.
pkg.sh — bash sourced by scripts/update-package.sh, providing:
- BUILD_DEPS — array of Arch packages installed before building,
- latest_version — prints the latest upstream version (no v prefix),
- build_artifact <version> <output-file> — downloads/builds upstream and writes the install tree (a tarball containing usr/) to <output-file>.

The workflow discovers package directories automatically. Trigger a run manually via Actions → Update AUR packages → Run workflow to publish it immediately.
