"""Shared skip-list handling for the Python adapters.

Load as a pytest plugin (`pytest -p e2e_skip`) and every test named in `$E2E_SKIP_LIST` is
skipped, so an adapter needs no skip code of its own. An adapter that must skip before
collection -- because the test would otherwise be generated at all -- calls `parse` directly.
