# This class is for packages which use the deprecated setuptools behaviour,
# specifically custom install tasks which don't work correctly with bdist_wheel.
# This behaviour is deprecated in setuptools[1] and won't work in the future, so
# all users of this should consider their options: pure Python modules can use a
# modern Python tool such as build[2], or packages which are doing more (such as
# installing init scripts) should use a fully-featured build system such as Meson.
