Add a 'per plugin type' specific subdirectory here, including ``module_utils`` which is usable not only by modules, but by most plugins by using their FQCN. This is a way to distribute modules, lookups, filters, and so on without having to import a role in every play.
Vars plugins are unsupported in collections. Cache plugins may be used in collections for fact caching, but are not supported for inventory plugins.
Vars plugins are supported in collections as long as they require being explicitly enabled (using ``REQUIRES_ENABLED``) and they are included using their fully qualified collection name. See :ref:`enable_vars` and :ref:`developing_vars_plugins` for details. Cache plugins may be used in collections for fact caching, but are not supported for inventory plugins.
