Usage:

  $0 [OPTIONS] TESTSDIR

Synopsis:

  Perform ALvisNLP regression test runs. TESTSDIR is the base directory
containing tests.
  This script compiles the provided sources of AlvisNLP, then installs it in
the working directory. Then tests are searched in subdirectories and each test
is run.

Options:

  -h, --help                    print help
  -a, --alvisnlp-sources=DIR    AlvisNLP sources directory
                                (default: $ALVISNLP_SRC)
  -n, --no-compile              do not compile AlvisNLP
  -f, --full-compile            compile as if Maven local repo was empty
  -w, --working-directory=DIR   base working directory for test runs
                                (default: $WORKING_DIR)
  -i, --include=NAME            include the specified test and exclude the
                                others. This option can be specified more than
                                once.
  -x, --exclude=NAME            exclude the specified test. This option can be
                                specified more than once.


Tests:

  The TESTSDIR directory must contain one sub-directory for each test. Each test
directory must contain a shell script file named \`test.sh'. This script is run
to perform the test with the \`errexit' option.
  This script exports two commodity functions:

    run-alvisnlp    runs AlvisNLP with the specified function. The input files
                    including the plan file are set to be searched in the test
                    directory, as well as the \`share' subdirectory of TESTSDIR.
                    The log file and the output files are set in this script
                    working directory.
                    Example: run-alvisnlp test.plan

    check-file      checks that a generated file is identical to a reference
                    file. The generated file must have been produced by a
                    AlvisNLP run. The reference file must be present in the test
                    directory. The first and second arguments specify the
                    reference and the generated file names respectively. If both
                    files have the same name, then the second argument may be
                    omitted.
