+-- buildsh-demo.recipe — demonstrates build_system = "build.sh".
+--
+-- The build.sh build system runs the source tree's build.sh script from the
+-- extracted source directory. The script receives $DESTDIR pointing at the
+-- staging tree where installed files must be placed, exactly like the
+-- 'custom' build system — but the script name is fixed to build.sh.
+--
+-- To try this:
+--   1. Unpack the source tarball:  tar -xzf buildsh-tool-1.0.tar.gz
+--   2. Run the script manually:     cd buildsh-tool-1.0 && DESTDIR=/tmp/stage sh build.sh
+--   3. Inspect the staged output:   find /tmp/stage
+--   4. Build with makepkg:          zeta-makepkg buildsh-demo.recipe
