/**
 * Generate content for a Drupal 6 database to test the upgrade process.
 *
 * @todo: Currently we use Drush for producing the script, find out why I wasn't
 * able to use just php-cli.
 *
 * Run this script at the root of an existing Drupal 6 installation.
 * Steps to use this generation script:
 * - Install Drupal 6.
 * - Install and enable Organic groups module.
 * - Copy from Drupal 7 includes/utility.inc to Drupal 6 includes folder (the
 *   include file is version agnostic).
 * - Execute script by running
 *     drush php-script generate-og-d6-content.php > drupal-6.og.database.php
 *   from the command line from the Drupal 6 ROOT directory.
 * - Since Organic groups module is a contrib module, it needs to be disabled
 *   for the upgrade path, thus open the result file with a text editor and
 *   under the {system} table, change the "status" value of the 'og' insertion
 *   to 0.
 *
 * This scripts produces the following scenario:
 * - Nid 1: Group without posts.
 * - Nid 2: Group with 3 posts (Nid 3 - 5).
 * - Nid 6: Orphan group content (i.e. not attached to a group).
 * - Nid 7, 8: Groups that share a group content (Nid 9).
 * - Nid 10: Group with members:
 *   - Uid 3: Group manager.
 *   - Uid 4: Pending member.
 *   - Uid 5: active member.
 *   - Uid 6: Pending admin member.
 *   - Uid 7: Active admin member.
