./validate.sh - build & test

Usage: ./validate.sh [ -j JOBS | -l | -C | -c | -s | -w HC | -x CABAL | -y CABALPLAN | -d | -v ]
  A script which runs all the tests.

Available options:
  -j JOBS        cabal v2-build -j argument (default: $JOBS)
  -l             Test Cabal-the-library only (default: $CABALONLY)
  -C             Don't run Cabal tests (default: $CABALTESTS)
  -c             Don't run cabal-install tests (default: $CABALINSTALLTESTS)
  -s             Don't run cabal-testsuite tests (default: $CABALSUITETESTS)
  -w HC          With compiler
  -x CABAL       With cabal-install
  -y CABALPLAN   With cabal-plan
  -d             Build dependencies only
