title: What is grails wrapper directory for?
body: <p>I created an app using create-app with Grails 2.3.7, I noticed there is a wrapper directory with jars inside.</p>
  
  <p>Isn't the dependecies are handled by maven(.m2) or ivy?</p>
  
  <p>What is it for? Why is it located inside the grails application and should I include it under version control?</p>
