# Complete tests of PLplot for the three generic build types which
# consist of shared+dynamic, shared+nondynamic, and
# static+nondynamic.  These complete tests that are run for each build
# type are (I) test_noninteractive, test_interactive, and ctest in the
# build tree; (II) traditional [Makefile+pkg-config]
# test_noninteractive and test_interactive of installed examples; and
# (III) CMake-based test_noninteractive and test_interactive of
# installed examples.

    echo "Usage: $prog [OPTIONS]
OPTIONS:
  The next option specifies the directory prefix (absolute or relative to
  the original directory from which this script was invoked) which controls
  where all files produced by this script are located.
  [--prefix (defaults to the 'comprehensive_test_disposeable'
                  subdirectory of the directory just above the
                  top-level source-tree directory)]

  The next option controls whether the shared, nondynamic, and static
  subdirectories of the prefix tree are initially removed so the
  tarball of all results is guaranteed not to contain stale results.
  Only use no for this option if you want to preserve results from a
  previous run of this script that will not be tested for this run,
  (e.g., if you previously used the option --do_shared yes and are now
  using the option --do_shared no).
  [--do_clean_first (yes/no, defaults to yes)]

  The next option controls whether the script runs clean to get rid of
  file results and save disk space after the tests are completed.
  This option is highly recommended to greatly reduce the
  the disk usage (which can be as large as 40GB [!] without this
  option).
  [--do_clean_as_you_go (yes/no, defaults to yes)]

  The next six options control the tools used for the configurations, builds, and tests.
  [--cmake_command (defaults to cmake)]
  [--generator_string (defaults to 'Unix Makefiles')]
  [--cmake_added_options (defaults to none, but can be used to specify any
                          combination of white-space-separated cmake options
                          to, e.g., refine what parts of the PLplot software are
                          built and tested)]
  [--build_command (defaults to 'make -j4')]
  [--ctest_command (defaults to 'ctest -j4')]
  [--do_submit_dashboard (yes/no defaults to no,  but if set to yes, the -D Experimental option
                      will be added to the ctest command, i.e., a dashboard of the ctest results
                      will be sent to <http://my.cdash.org/index.php?project=PLplot_git> where
                      they will be publicly displayed.]

  The next three options control which of the three principal PLplot configurations are tested.
  [--do_shared (yes/no, defaults to yes)]
  [--do_nondynamic (yes/no, defaults to yes)]
  [--do_static (yes/no, defaults to yes)]

  The next six control which of seven kinds of tests are done for
  each kind of build.
  [--do_test_interactive (yes/no, defaults to yes)]
  [--do_test_noninteractive (yes/no, defaults to yes)]
  [--do_ctest (yes/no, defaults to yes)]
  [--do_test_build_tree (yes/no, defaults to yes)]
  [--do_test_install_tree (yes/no, defaults to yes)]
  [--do_test_traditional_install_tree (yes/no, defaults to yes)]
