+This works around an incompatibility in node versioning policies between Backstage and
+the openid-client package. This script downloads a target version of the openid-client
+package and re-publishes it as a new version of the openid-client-any-engine package.

+Usage: ./republish-openid-client.js <version>
+
+Environment Variables:
+
+NPM_TOKEN: The NPM auth token to use for publishing.
+NPM_OTP: The NPM OTP (2FA one time password) to use for publishing.
