+# Uploads firecracker-{amd64,arm64} assets from a fc-versions GitHub release
+# to GCS at:
+#   <bucket>/<version_name>/<arch>/firecracker
+#
+# Existing objects are never overwritten.
+#
+# Usage:
+#   ./scripts/upload-release-to-gcs.sh --tag <tag> --bucket <bucket> [--dry-run] [--repo <repo>]
+#
+# Options:
+#   --tag <tag>        Release tag / version name (e.g. v1.14.1_af9c995).
+#   --bucket <bucket>  Target bucket (with optional path prefix), e.g.
+#                        my-bucket
+#                        my-bucket/firecrackers
+#                        gs://my-bucket/firecrackers
+#   --repo <repo>      GitHub repo (default: e2b-dev/fc-versions).
+#   --dry-run          Print what would be uploaded without writing.
+#   -h, --help         Show this help.
