+# This is a helper script for Knative release scripts. To use it:
+# 1. Source this script.
+# 2. Call the parse_flags() function passing $@ (without quotes).
+# 3. Call the run_validation_tests() passing the script or executable that
+#    runs the release validation tests.
+# 4. Write logic for the release process. Use the following boolean (0 is
+#    false, 1 is true) environment variables for the logic:
+#    SKIP_TESTS: true if --skip-tests is passed. This is handled automatically
+#                by the run_validation_tests() function.
+#    TAG_RELEASE: true if --tag-release is passed. In this case, the
+#                 environment variable TAG will contain the release tag in the
+#                 form vYYYYMMDD-<commit_short_hash>.
+#    PUBLISH_RELEASE: true if --publish is passed. In this case, the environment
+#                     variable KO_FLAGS will be updated with the -L option.
+#    SKIP_TESTS, TAG_RELEASE and PUBLISH_RELEASE default to false for safety.
+#    All environment variables above, except KO_FLAGS, are marked read-only once
+#    parse_flags() is called.
