+-- hooks-demo.recipe — demonstrates shipping a post-transaction hook.
+--
+-- The custom build script installs a small command and a hook file under
+-- usr/share/zeta/hooks/.  zeta-makepkg scans the stage for *.hook files,
+-- validates each one (a hook is a pure-data Lua table carrying `trigger`
+-- and `action`), and merges the found paths into the generated `files`
+-- whitelist so the hook is committed alongside the declared files.
+--
+-- To try this:
+--   1. Unpack the source tarball:  tar -xzf hooks-demo-1.0.tar.gz
+--   2. Run the script manually:     cd hooks-demo-1.0 && DESTDIR=/tmp/stage sh build.sh
+--   3. Inspect the staged output:   find /tmp/stage
+--   4. Build with makepkg:          zeta-makepkg hooks-demo.recipe
