title: Remove large files on BitBucket
body: <p>I have accidentally committed a large file on BitBucket. Cloning the repository on low ram embedded systems causes me an out of memory exception.</p>
  
  <p>I would remove the huge file from the server, or export the history locally to a revision prior the commit, and then push it again to BitBucket.</p>
  
  <p>How can accomplish this?</p>
  
  <p>Regards,
  Antonio</p>
