+
+### retryable([opts = {times: 5, interval: 0}| 5], task)
+
+A close relative of `retry`.  This method wraps a task and makes it retryable, rather than immediately calling it with retries.
+
+__Arguments__
+
+* `opts` - optional options, exactly the same as from `retry`
+* `task` - the asynchronous function to wrap
+
+__Example__
+
+```js
+async.auto({
+    dep1: async.retryable(3, getFromFlakyService),
+    process: ["dep1", async.retryable(3, function (results, cb) {
+        maybeProcessData(results.dep1, cb)
+    })]
+}, callback)
+```
