It's your turn to have conflict with @brouberol ^^ Can you fix it in __main__.py please ?

By the way it's a very good and useful (I think) PR, but I have 2 comments :

• originally the tool was designed to be simple, now we have many options for a single feature, (--server, --server-host, --server-port). Can you merge it in 1 single option to have a cleaner help ?
  Example : whatportis --server 127.0.0.1 8000 instead of whatportis --server --server-host=127.0.0.1 --server-port=8000. It's very simple with click (http://click.pocoo.org/5/options/#multi-value-options).
• and can you update the README to inform users about this new feature please ? For example telling them how to launch the server, and 1 or 2 curl examples (curl 127.0.0.1:8080/ports/5432, curl 127.0.0.1:8080/ports/mysql?like).

Thank you :)

It's updated now ;)

Arff, apparently click does not support default values for narg > 1 (pallets/click#472 (comment)) !
I merge it anyway, thanks 👍

I know - that's why I implemented it the way I did ;) 🍻
