# Lithium are quite protective of data, there is no simple way of exporting
# If you have leverage you may get a data dump, in my case it was provided in XML
# format
#
# First step is to convert it to db format so you can import it into a DB
# that was done using import_scripts/support/convert_mysql_xml_to_mysql.rb
