    ## macOS on Travis is tricky:
    ##   - We use the default python version on macOS, which is currently 2.7.
    ##     (But we don't show the version, because Travis might change it
    ##     without us noticing.)
    ##   - We use language: c, because language: python fails on Travis macOS.
    ##   - We get the tor version in the homebrew cache on the macOS image.
    ##     The latest tor version in homebrew is on this page:
    ##       https://formulae.brew.sh/formula/tor
    ##     The Travis version might be slightly older.

    ## Test all supported and available tor versions on Linux
    ## If the deb.torproject.org repositories are removed, we will fall back to

    ## automatically fail the job if we can't get a newer tor, see #29741.
