meetup's API Key not supported anymore, need to use OAuth2 instead

[pinage404]

Hi,

I'm trying to use this software for the first time

i ran :

meetup-cli
It looks like you are running meetup-cli for the first time.

Obtain an API key from: https://secure.meetup.com/meetup_api/key/

And save the following in ~/.meetup-clirc:

api_key: <api-key>

so i went to https://secure.meetup.com/meetup_api/key/

the page shows this message :

Getting an API

This feature is no longer actively supported. As an alternative, you can use OAuth2

[specious]

Everything needs to be updated to use the new API.
