+# PKGBUILD for the linux-unstable-ogc kernel.
+#
+# It is designed to be built by the CI job defined in
+# .github/workflows/build-kernel.yml, which stages the following next to this
+# file before invoking makepkg:
+#   - linux.tar.gz     -> tarball of the checked-out kernel tree (no VCS data)
+#   - config           -> Arch linux-headers .config with the OGC
+#                         kernel-packages config fragments already applied
+#   - config.fragment  -> repo-local overrides merged on top of it
+#
+# Based on the official Arch Linux kernel PKGBUILD and on the (known to work
+# with linux-next) https://github.com/NeroReflex/linux-bisector PKGBUILD.
