+# One stop build of shortfin Python package for Linux. The Linux build is
+# complicated because it has to be done via a manylinux docker container.
+#
+# Usage:
+# Build everything (all python versions):
+#   sudo ./build_tools/build_linux_package.sh
+#
+# Build specific Python versions to custom directory:
+#   OVERRIDE_PYTHON_VERSIONS="cp312-cp312 cp313-cp313" \
+#   OUTPUT_DIR="/tmp/wheelhouse" \
+#   sudo -E ./build_tools/build_linux_package.sh
+#
+# Valid Python versions match a subdirectory under /opt/python in the docker
+# image. Typically:
+#   cp312-cp312 cp313-cp313
+#
+# Note that this script is meant to be run on CI and it will pollute both the
+# output directory and in-tree build/ directories with docker created, root
+# owned builds. Sorry - there is no good way around it.
+#
+# It can be run on a workstation but recommend using a git worktree dedicated
+# to packaging to avoid stomping on development artifacts.
