title: can i delete .repo after repo sync is successfull?
body: <p>I'm trying to port Lollipop on snapdragon 8074, And i'm running low on disk space.
  So i was thinking of deleting the .repo directory after repo sync is successfully done, to make some space for building the source code.</p>
  
  <p>Is it necessary to keep the .repo after the source code is downloaded.?</p>
  
  <p>Thank you.</p>
