This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.


This package can be used for renewal of expiring access tokens according to user-provided actions. Tokens will be stored in a transactional variable (TVar).
