title: Gogs access repository files to use lftp in an hook
body: <p>I'm using gogs as a git server on a Raspberry. I'd like to create a post-receive git hook to upload changes on my remote server (which I can access only via FTP). 
  I think I can use lftp but the thing is that I don't know how to find my php files on my raspberry. When I go to my repository folder I don't have these files but some files like :  d81e2a2ed01b13b4117e59338b239137c81901</p>
  
  <p>How can I proceed ? </p>
  
  <p>Thanks, 
  Thombou</p>
