-
-This is a Go port of the exponential backoff algorithm from [Google's HTTP Client Library for Java][google-http-java-client].
-
-[Exponential backoff][exponential backoff wiki]
-is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
-in order to gradually find an acceptable rate.
-The retries exponentially increase and stop increasing when a certain threshold is met.
-
-## Usage
