======================================

gem install xmpp4r_facebook

======================================
Sample code:
======================================
require 'xmpp4r_facebook'

id = '-<sender user id>@chat.facebook.com'
to = '-<user id>@chat.facebook.com'
body = "hello, Im not spam!"
subject = 'message from ruby'
message = Jabber::Message.new to, body
message.subject = subject

client = Jabber::Client.new Jabber::JID.new(id)
client.connect
client.auth_sasl(Jabber::SASL::XFacebookPlatform.new(client, '<App ID/API Key>', '<Access Token>', '<App Secret>'), nil)
client.send message
client.close

Ensure your access token has `xmpp_login` permission. Check at https://developers.facebook.com/tools/debug
