    27  	Short: `Checks the files in the source and destination match.`,
    28  	Long: `
    29  Checks the files in the source and destination match.  It compares
    30  sizes and hashes (MD5 or SHA1) and logs a report of files which don't
    31  match.  It doesn't alter the source or destination.
    32  
    33  If you supply the --size-only flag, it will only compare the sizes not
    34  the hashes as well.  Use this for a quick check.
    35  
    36  If you supply the --download flag, it will download the data from
    37  both remotes and check them against each other on the fly.  This can
    38  be useful for remotes that don't support hashes or if you really want
    39  to check all the data.
    40  
    41  If you supply the --one-way flag, it will only check that files in source
    42  match the files in destination, not the other way around. Meaning extra files in
    43  destination that are not in the source will not trigger an error.
