ruby-retryable - 2.0.4-1 main

Runs a code block, and retries it when an exception occurs. It's great when
working with flakey webservices (for example).
.
It's configured using four optional parameters :tries, :on, :sleep, :matching,
:ensure, :exception_cb and runs the passed block. Should an exception occur,
it'll retry for (n-1) times.
.
Should the number of retries be reached without success, the last exception
will be raised.
