Okay, I think I finally excised the ghosts in the multiarch jenkins build for this... |

Note for reviewers: The review is probably easiest to do commit-by-commit, with the actual code changes all happening in the first commit. The second is some documentation, which can be reviewed, and the third is the result of a lot of jenkins tweaking to keep the build happy, which can probably be skipped if you're willing to trust the fact that it is building. |

This crashes if the provided --debug-data-file cannot be read. Do we have an existing test for that? Looks like test/integration/cli-args/debug-generate-data.t only has error cases where either no data file is provided or the file is well-formed JSON that does not contain the expected data.

Fixed this, and a separate issue where it would crash if the file existed, but could not be opened

I don't know anything about Jenkins, but what's the reason for the tag change?

I needed to re-build the multiarch images to add cmdliner. Because they don't install the developer-only dependencies like ocamlformat, I guess they didn't have it already.
This was a headache, and it's definitely non-obvious how the multiarch build works, see #1480

I mentioned this in #1477. The use of imperative style argument parsing in
stanc.exeled to some weird code patterns and didn't give us type-checking guarantees about each setting actually being available (or, conversely, being used).This PR switches to using the
cmdlinerlibrary: https://erratique.ch/software/cmdliner. This is by the same author as thefmtlibrary we already use, and is used byopamitself. I think it might already be installed on most of our switches as a result, but if not it's a very minimal addition.Submission Checklist
Release notes
Improved the command-line argument parser for
stanc. Existing flags are still supported, but new aliases may be available. See the new and improvedstanc --helpfor details.Copyright and Licensing
