Possible options, besides `--dot`:
* --verbose or -v: Makes the program more talkative
* --debug: Makes the program very talkative (sets verbose to true)
* --head or -e: (DoH) Uses only the HEAD HTTP method. Since the RFC
does not mention it, result is probably indefinite.
* --POST or -P: (DoH) Uses the POST HTTP method (default is GET)

* --pipelining: on DoT, send several requests even before getting the
reply to the first one (may increase performance when you have
several requests)
* --multistreams: (DoH) Uses HTTP/2 streams (requires the --file option)
* --file INPUT_FILE: provide an input file with a list of domain name to query
(read the first line only, use --repeat N to read up to N lines of the file)

### Check
The `--check` option allows to run several defined tests on a connection.

When repeating tests, you can add a delay between tests, with `--delay
N`, where N is the (possibly fractional) number of seconds to wait.
N` or `-d N`, where N is the (possibly fractional) number of seconds
to wait.
### Mulitstreams
When using Homer with DoH, the option `--multistreams` can be used
to specify that you want to take advantage of the HTTP/2 streams
when sending several requests.
This option requires an input file provided with the `--file` option.
By default only the first line of the file is read. You need to
specify a number of line with `--repeat` to read more lines from
the file.
For example :
```
% ./homer.py --multistreams --file input_file --repeat 5 https://doh.powerdns.org
```
In order to focus on the time per request, you can suppress the
output by using the option `--no-display-results`.
This option only works with `--multistreams`.
Two modes are available. By default each response is read,
checked and displayed as soon as it is received.
You can use `--sync` to delay this processing after the last transfer.
In that case the DNS responses are displayed in the same order as they
were sent.
An option `--time` allows to display the time taken by each transfer.
This is based on [libcurl time values](https://curl.haxx.se/libcurl/c/curl_easy_getinfo.html#TIMES)
[CURLINFO_TOTAL_TIME](https://curl.haxx.se/libcurl/c/curl_easy_getinfo.html#CURLINFOTOTALTIME)
and [CURLINFO_PRETRANSFER_TIME](https://curl.haxx.se/libcurl/c/curl_easy_getinfo.html#CURLINFOPRETRANSFERTIME)
```
% ./homer.py --multistreams --file input_file --repeat 5 --no-display-results --time https://doh.powerdns.org
