title: Liferay 7 disable features/modules
body: <p>Liferay 7 is based on OSGi modules.</p>
  
  <p>Therefore... Is it possible to disable some modules/features in order to have a lightweight liferay install. For instance : disable wiki pages or forums...because my project doesn't need this features.</p>
  
  <p>How can this be done?</p>
