A Magento shell script to automatically create an attribute migration script for a specific attribute. This allows developers to tweak their attributes in the UI, and then generate a script for deployment.
###Magento Attribute Migration Generator
This script generates a setup resource script for any existing Magento attribute.
./magento-create-setup.php attribute_code
NOTE: Must be run from the root of the Magento system with the existing attribute.
