+# Install the prebuilt CPU-only vLLM wheel (`vllm-cpu-nightly`) plus a
+# `vllm-<ver>+cpu.dist-info` alias.
+#
+# Why the alias: the wheel installs the `vllm/` package but registers
+# its dist metadata under `vllm-cpu-nightly`. vLLM's CLI / internal
+# callers do `importlib.metadata.version("vllm")` (distribution name,
+# not import name); without the alias that raises PackageNotFoundError
+# and `vllm serve` won't start. The `+cpu` local label is also needed
+# so `cpu_platform_plugin()` activates the CPU platform (it greps the
+# dist metadata for the substring "cpu"); our build strips `+cpu`
+# before PyPI upload because PyPI rejects local versions.
+#
+# Usage:
+#   install_vllm_cpu.sh           # use plain `pip`
+#   PIP_BIN="uv pip" install_vllm_cpu.sh
+#                                 # use `uv pip` and pass extra flags
+#                                 # via PIP_INSTALL_EXTRA_ARGS
+#
+# Idempotent: re-running just rewrites the alias.
