* Lang now verifies errors and parse output * Some new miscellaneous tests * Easy way to update the tests * Document workflow in manual * Use `!` not `~` as separater char for sed It is confusing to use `~` when we are talking about paths and home directories! * Test test suite itself (`test/lang-test/infra.sh`) Additionally, run shellcheck on `tests/lang.sh` to help ensure it is correct, now that is is more complex.
