+# This script will query github on every invocation to pull the latest released version
+# of openapi-generator.
+#
+# If you want repeatable executions, you can explicitly set a version via
+#    OPENAPI_GENERATOR_VERSION
+# e.g. (in Bash)
+#    export OPENAPI_GENERATOR_VERSION=3.1.0
+#    openapi-generator-cli.sh
+# or
+#    OPENAPI_GENERATOR_VERSION=3.1.0 openapi-generator-cli.sh
+#
+# This is also helpful, for example, if you want want to evaluate a SNAPSHOT version.
+#
+# NOTE: Jars are downloaded on demand from maven into the same directory as this script
+# for every 'latest' version pulled from github. Consider putting this under its own directory.
