To enable the sortable module add

1. create the sf_sortable table in your database

CREATE TABLE `sf_sortable`
(
        `sortable_id` INTEGER  NOT NULL AUTO_INCREMENT,
        `list_name` VARCHAR(40)  NOT NULL,
        `object_id` INTEGER  NOT NULL,
        `sort_val` INTEGER  NOT NULL,
        PRIMARY KEY (`sortable_id`),
        KEY `list`(`list_name`, `sort_val`, `object_id`)
)Type=MyISAM;


2. configure your modules using the admin generator.yml 

  param:
    model_class:      Title
    theme:            sortable << change the theme

...    

    list:
      object_actions:
       _moveUp: - 					<< add this action
       _moveDown: -					<< and this 
       _edit: -
       _delete: -

3. To use the nav icons, link or copy the images from  
 plugins/sfPropelManualOrderePlugin/web/images/* to web/sf/sf_admin/images/			

Notes 

  * the plugin is designed for ease of use with the admin generator

  * works with int primary keys 

  * doesn't enforce consistency (but inconsistencies don't break it)

  * is inefficient for high transaction volumes or large lists

  * is not concurrency safe

  * there's an excellent tutorial on how to do manual order:
	http://web.archive.org/web/20060519130448/http://www.symfony-project.com/content/book/page/sortable.html

  * icons are thanks to Mark James' great 'Silk' icon set:
  http://www.famfamfam.com/lab/icons/silk/

  * you can add sort functions into your model classes e.g. in
  lib/model/MyClass.php, add the lines: 
	// add moveUp, moveDown, toTop, toBottom, getSortPosition,
	// getSortedList
	sfSortablePeer::addSortFunctions('MyClass'); //(uses sfMixer/__call)
