 +=== Batch by drush ===
 +== Sources ==
 +  * http://www.metaltoad.com/blog/using-drupal-batch-api
 +  * http://victorquinn.com/blog/2012/08/11/programmatically-creating-fielded-d7-nodes/
 +== How ? ==
 +I needed to import some content from a Joomla! website. I have exported the content using phpmyadmin and asking to get the data as a php array from the table 'jos_content' and get only the fields named :
 +  * title
 +  * introtext
 +  * fulltext
 +  * state
 +  * created
 +  * created_by
 +  * modified
 +Then, i have used a drush script to import them. It tooks about 30 seconds for 280 nodes. The exported file was 1.2MB
 +== Code ==

 +~/.drush/bash_import.drush.inc
