+# Invoked from the extracted source directory.  The tool sets:
+#   $DESTDIR  → staging tree root (e.g. /tmp/zeta-makepkg/hooks-demo-.../stage)
+#
+# This script installs a small command under usr/bin/ and a post-transaction
+# hook under usr/share/zeta/hooks/.  A hook is a pure-data Lua file:
+#
+#   return {
+#     order   = 50,
+#     trigger = { op = "install", type = "package", target = { "hooks-demo" } },
+#     action  = { when = "post", exec = "true", description = "example hook" },
+#   }
+#
+# zeta-makepkg scans the stage for usr/share/zeta/hooks/*.hook, validates the
+# format, and merges the paths into the generated `files` whitelist.
