Programmatic Drupal CCK node creation from CSV files using node_save()

gistfile1.php

<?php
/* The long and the short of it, for Drupal 6 - use content_insert(), which
should be fired anyway but isn't. See "node_save() with CCK fields" [1] for
more details. drupal_execute() is too robust for me - I just needed to import
a SQL Server table with 4500+ rows quickly. Requires parsecsv for PHP [2].
