How to use Doctrine Extensions: Timestampable, Sluggable, Translatable, etc.

Doctrine2 is very flexible, and the community has already created a series of useful Doctrine extensions to help you with common entity-related tasks.

One library in particular - the DoctrineExtensions library - provides integration functionality for Sluggable, Translatable, Timestampable, Loggable, Tree and Sortable behaviors.
