Rules Extra Tokens is a tiny module that contains a Rules Action to make the contents of a cookie or session variable available as a token, [cookie:value] or [session:value], for use in subsequent Actions in the same Rule.
No other tokens are supplied at this stage.
This module is very much related to and could (should?) be merged with:
Trigger drush tasks from actions taken on the website!
What? Are we in bizzaro-land here? Normally drush is the tool you use to do things to your Drupal! But what if you wanted Drupal to do something to your drush?
Now you can!
This module provides a new "Drush Task" that is an action that can be triggered by "Rules".
Once it's set up (there can be some glitches, and it may not work on all hosting environments) you can run drush commands when things happen!
