+# To run a specific Ruby test, set $workbench_test, $apiserver_test or
+# $cli_test on the command line:
+#
+# $ run-tests.sh --only workbench workbench_test=TEST=test/integration/pipeline_instances_test.rb
+#
+#
+# To run a specific Python test set $python_sdk_test or $fuse_test.
+#
+# $ run-tests.sh --only python_sdk python_sdk_test="--test-suite tests.test_keep_locator"
+#
+#
+# You can also pass "export ARVADOS_DEBUG=1" to enable additional debugging output:
+#
+# $ run-tests.sh "export ARVADOS_DEBUG=1"
+#
+#
+# Finally, you can skip the installation steps on subsequent runs this way:
+#
+## First run
+# $ run-tests.sh --leave-temp
+#
+## Subsequent runs: record the values of VENVDIR and GOPATH from the first run, and
+# provide them on the command line in subsequent runs:
+#
+# $ run-tests.sh --skip-install VENVDIR="/tmp/tmp.y3tsTmigio" GOPATH="/tmp/tmp.3r4sSA9F3l"
