Test cases to check Coq's flag setting is correct:

  $ cat > dune-project <<EOF
  > (lang dune 2.8)
  > (using coq 0.3)
  > EOF

  $ cat > foo.v <<EOF
  > Definition t := 3.
  > EOF

Test case: default flags

  $ cat > dune <<EOF
  > (coq.theory
  >  (name foo))
  > EOF

  $ dune build foo.vo && tail -n 1 _build/log | ./scrub_coq_args.sh
