##[

avoid code duplication in CI pipelines.

For now, this is only used for openbsd + freebsd, but there is a lot of other code

duplication that could be removed.

## usage

edit this file as needed and then re-generate via:

```

nim r tools/ci_generate.nim

```

const doNotEdit = "DO NO EDIT DIRECTLY! auto-generated by `nim r tools/ci_generate.nim`"
