  Function decoration for backoff and retry
  
  This module provides function decorators which can be used to wrap a
  function such that it will be retried until some condition is met. It
  is meant to be of use when accessing unreliable resources with the
  potential for intermittent failures i.e. network resources and external
  APIs. Somewhat more generally, it may also be of use for dynamically
  polling resources for externally generated content.
  
  For examples and full documentation see the README at
