title: What are the options available for Doctrine's Doctrine_Core::generateModelsFromDb method?
body: <p>Doctrine 1.2 has a method called generateModelFromDb, <a href="http://www.doctrine-project.org/Doctrine_Core/1_2#method_generatemodelsfromdb" rel="noreferrer">documented here</a>, that generates model files for all of the tables in a database.</p>
  
  <p>This function accepts an optional third parameter with an array of "options" to use when generating models, the specifics of which are not documented. What options are available for me to specify here?</p>
