I'm using this to do an export of users from an eZ 3.x install to be imported into a 4.2 install. I've cleaned up a bunch of the parsers and am making them mirror the output of the toString methods are are now in ez 4.2 datatypes. See: http://ezpedia.org/en/ez/simple_f...nd_tostring_interface_for_attributes
This should allow easier imports using the ezcsvimport.php script.
