-<B>RETRY STRATEGY</B>
-  There are a number of reasons that gsutil operations can fail; some are not
-  retryable, and require that the user take some action, for example:
-    - Invalid credentials
-    - Network unreachable because of a proxy configuration problem
-    - Access denied, because the bucket or object you are trying to use has an
-      ACL that doesn't permit the action you're trying to perform.
-
-  In other cases errors are retryable - basically, the HTTP 429 and 5xx error
-  codes. For these cases, gsutil will retry using a truncated binary exponential
-  backoff strategy:
-
-    - Wait a random period between [0..1] seconds and retry;
-    - If that fails, wait a random period between [0..2] seconds and retry;
-    - If that fails, wait a random period between [0..4] seconds and retry;
-    - And so on, up to a configurable maximum number of retries (default = 6),
-    with each retry period bounded by a configurable maximum period of time
-    (default = 60 seconds).
-
-  Thus, by default, gsutil will retry 6 times over 1+2+4+8+16+32=63 seconds.
-  You can adjust the number of retries and maximum delay of any individual retry
-  by editing the num_retries and max_retry_delay configuration variables in the
-  "[Boto]" section of the .boto config file. Most users shouldn't need to change
-  these values.
-
-  For data transfers (the gsutil cp and rsync commands), gsutil provides
-  additional retry functionality, in the form of resumable transfers.
-  Essentially, a transfer that was interrupted because of a transient error
-  can be restarted without starting over from scratch. For more details
-  about this, see the "RESUMABLE TRANSFERS" section of "gsutil help cp".
