+# moonlight-vrr - Nonary's fork of Moonlight (https://github.com/Nonary/moonlight-qt),
+# the GameStream client for PCs, with smooth VRR frame pacing (C++ + Qt6).
+#
+# Source package: the PKGBUILD builds the release tag against Arch's Qt6 and
+# FFmpeg, as extra/moonlight-qt does for the original. moonlight-vrr-bin
+# repackages the AppImage upstream builds from the same tag.
+#
+# The tag tarball lacks the git submodules. refresh_checksums() reads the
+# commit of each from the tag's tree (enet and nanors from moonlight-common-c)
+# and syncs it into the PKGBUILD. It fails when a submodule moves to another
+# repository.
+#
+# Tags look like v6.1.0-vrr18, pkgver has an underscore for the hyphen.
+# /releases/latest skips the betas, which upstream marks as prereleases.
+
+UPSTREAM_REPO="Nonary/moonlight-qt"
+
+# Installed in CI (pacman) before the makepkg test build: the makedepends plus
+# the libraries the build links against. qmake turns off what it cannot find.
