Writing a Module

Abstract

In many open source applications, you can customize the application by modifying the source code. While this is one method for getting the behavior you desire, it is generally frowned upon and considered a last resort in the Drupal community. Customizing code means that with each update of Drupal, you must perform more work—you must test to see that your customization still works as expected. Instead, Drupal is designed from the ground up to be modular and extensible.
