Please note that TableTools has now been retired and replaced by the Buttons and Select extensions which offers significant improvements and API integration with the rest of DataTables and the other extensions.
Thanks - I'm not going to pull this in just yet and I need to make a proper plan for the various package managers for all of my software which I hope to make time to do soon.
This is along the same lines as https://github.com/DataTables/DataTables/pull/485 :)
