title: Eclipse RCP: Actions VS Commands
body: <p>What are differences between Actions and Commands in the context of Eclipse RCP?  I know that they both contribute to the menu entries, but which one is better?  And why?</p>
  
  <p>Of all the online resources I read, I could not get a firm understanding of the differences between both.  I have not actually tried to use them, but just wanted to understand them to start with from higher level point of view.</p>
  
  <p>Thanks</p>
