# This is a directory used as TMPDIR, where pip copies sources to and builds from, relative to PWD
# For proper debugsource packages, we create TMPDIR within PWD
# See https://github.com/pypa/pip/issues/7555#issuecomment-595180864

# This will be used in debugsource package paths (applies to extension modules only)
# NB: pytest collects tests from here if not hidden
