-The release project's services run on commit and can be re-triggered via
-`osc service remoterun`. Trigger promptly after tagging, before further
-commits land. The dev project builds from HEAD on each trigger.
-
-**How it works:**
-
-1. The `_service` file tells OBS to:
-   - Fetch the source tarball from the upstream GitHub repository via `tar_scm`
-   - Extract the RPM spec, Arch PKGBUILD, and Debian packaging files via
-     `extract_file`
-   - Set the version via `set_version`
-2. OBS builds packages using each distro's native toolchain
-   (`dpkg-buildpackage`, `rpmbuild`, `makepkg`)
-
 **Packaging files:**
 
-- `debian/`                                    - Debian packaging (must be at
-  repo root for `dpkg-buildpackage`)
+- `debian/`                                             - DEB packaging
 - `packaging-examples/rpm-based/postscriptbarcode.spec` - RPM spec file
-- `packaging-examples/arch-linux/PKGBUILD`     - Arch PKGBUILD
-- `packaging-examples/open-build-service/`     - OBS-specific files
-  (`_service.release`, `_service.dev`, `.dsc`, `debtransform`)
-
-**Version handling:**
-
-The RPM spec and Arch PKGBUILD have empty version fields that OBS's
-`set_version` service fills at build time. The `CHANGES` file line 1 is
-`XXXX-XX-XX` between releases; build scripts (`setup.py`, `Makefile.PL`,
-`libs/c/Makefile`, `libs/bindings/Makefile`) skip this placeholder and use the
-first line starting with a digit.
+- `packaging-examples/arch-linux/PKGBUILD`              - Arch packaging

+**Package test scripts:**
 
-- `run_all.sh`          - Top-level runner; exits non-zero on any skip or failure
 - `test_postscript.sh`  - Loads `barcode.ps` in GhostScript and generates a barcode
-- `test_clib.sh`        - Tests C shared library via python3 ctypes
-- `test_python.sh`      - Tests Python binding via installed example
