+# plezy-bin - Plezy (https://github.com/edde746/plezy), a Plex, Jellyfin and
+# Emby client built with Flutter.
+#
+# Upstream builds the Linux release itself and publishes a .deb (plus .rpm,
+# .pkg.tar.zst and a portable tarball) per release, so there is no build step
+# here: on a new version only pkgver and the two checksums are refreshed and
+# the PKGBUILD repackages the .deb directly.
+#
+# plezy itself is in [extra], built from source by an Arch packager, so only
+# the -bin variant belongs in the AUR - a second source package would be a
+# duplicate the AUR rejects outright. The two conflict, and plezy-bin provides
+# plezy so either one satisfies a dependency on it. What it buys over the
+# repository package is release-day updates without the Flutter build, which
+# needs an fvm-pinned SDK and takes the better part of an hour.
+#
+# Release tags are plain versions with no v prefix (2.16.0), every release is a
+# full release, and the asset names are fixed (plezy-linux-x64.deb /
+# plezy-linux-arm64.deb), so /releases/latest is enough to track upstream.
