[development] Module to create and populate CCK nodes from existing database table

[Clemens Tolboom]

You could use node_factory module (not tested for D6) and if you want
command line interface you can use drush.

node_factory knows a few cck fields, og, free format tags

With drush you can insert your nodes from the command line too.

drush nf create json 'json-string'

If you are willing to test node_factory for D6 I will apply your
findings asap :-)
