    module Agents class JabberAgent < Agent include LongRunnable include FormConfigurable cannot_be_scheduled! gem_dependency_check { defined?(Jabber) } description <<-MD The Jabber Agent will send any events it receives to your Jabber/XMPP IM account. #{'## Include `xmpp4r` in your Gemfile to use this Agent!' if dependencies_missing?} Specify the `jabber_server` and `jabber_port` for your Jabber server. The `message` is sent from `jabber_sender` to `jaber_receiver`. This message can contain any keys found in the source's payload, escaped using double curly braces. ex: `"News Story: {{title}}: {{url}}"` When `connect_to_receiver` is set to true, the JabberAgent will emit an event for every message it receives. Have a look at the [Wiki](https://github.com/cantino/huginn/wiki/Formatting-Events-using-Liquid) to learn more about liquid templating.
