| Write the received protocol headers to the specified file. If no headers are |
| received, the use of this option will create an empty file. |
| |
| When used in FTP, the FTP server response lines are considered being "headers" |
| and thus are saved there. |

| Having multiple transfers in one set of operations (i.e. the URLs in one |
| --next clause), will append them to the same file, separated by a blank line. |
