               before the entire transfer is complete (e.g. failing after 300 of
               1000 files have been transferred), you will need to restart the
               entire transfer.
 
               Also, although most commands will normally fail upon encountering
               an error when the -m flag is disabled, all commands will
               continue to try all operations when -m is enabled with multiple
               threads or processes, and the number of failed operations (if any)
               will be reported at the end of the command's execution.
 
-              WARNING: If you use the gsutil -m option when copying data
-              between versioned buckets, object version ordering will not be
-              preserved. For more information see the
-              "COPYING VERSIONED BUCKETS" section under
-              'gsutil help versions'.

   -o          Set/override values in the boto configuration value, in the format
               <section>:<name>=<value>, e.g. gsutil -o "Boto:proxy=host" ...
               This will not pass the option to gsutil integration tests, which
               run in a separate process.
 
   -q          Causes gsutil to perform operations quietly, i.e., without
               reporting progress indicators of files being copied or removed,
               etc. Errors are still reported. This option can be useful for
               running gsutil from a cron job that logs its output to a file, for
               which the only information desired in the log is failures.
