Thanks for that pointer @saul. Documentation useful to script writers seems scarce.

If reading the example script documentation closely, please note that [some exit code documentation](https://github.com/duplicati/duplicati/commit/494fccd9316da42c0e65ad8527902ced4f7733af#diff-f83ec220518399c268dd34f54eab1e45) from that script is not in beta just yet (only in canary). See [Improvements for –run-script-before/after options](https://forum.duplicati.com/t/improvements-for-run-script-before-after-options/519) for history and some other links to scripting information.
