Create Drupal patches with Aptana, a tutorial

Patches are a kind of text file that describe the changes in a way that lets them easily be applied to the official code base. To create them, you have to jump through a couple of hoops, especially checking out Drupal head from CVS and creating the actual patch from the changes you made.
