title: Purpose of MANIFEST file on WAR files
body: <p>In a very general way I understand what's the purpose of the MANIFEST file in JAR files, it's to specify the MainClass and other metadata that I'm not aware of.</p>
  
  <p>I'd like to know if there's a more general definition of the purpose of this file, for example, <strong>in a <em>WAR</em> file what would be the use of it</strong>?</p>
  
  <p>Thanks a lot.</p>
