The directory can be obtained using $galaxyData.extra_files_path (be
sure to check it exists before zipping it up).

I would discourage re-using Galaxy components directly from inside of
a tool or tool wrapper - but if you want to reference that code it is
actually inside of the datatypes module -

Hope this helps.
