- quiet: Do not print messages to stdout.
- ratelimit: Download speed limit, in bytes/sec.
- retries: Number of times to retry for HTTP error 5xx
- buffersize: Size of download buffer in bytes.
- noresizebuffer: Do not automatically resize the download buffer.
- continuedl: Try to continue downloads if possible.
- noprogress: Do not print the progress bar.
- logtostderr: Log messages to stderr instead of stdout.
- consoletitle: Display progress in console window's titlebar.
- nopart: Do not use temporary .part files.
- updatetime: Use the Last-modified header to set output file timestamps.
