"""Fallback: re-export the original pure-Python ClusterShell modules.

This sub-package is a symlink/copy bridge so that any symbol not yet
ported to Rust can be imported from `ClusterShell._py.ModuleName`.
The actual source lives in the sibling consortium-tests repo at
`lib/ClusterShell/` (legacy monorepo layout: repo-root `lib/`).
